In btrfs_read_block_groups(), if we have an invalid block group which
has mixed type (DATA|METADATA) while the fs doesn't have MIXED_GROUPS
feature, we error out without freeing the block group cache.
This patch will add the missing btrfs_put_block_group() to prevent
memory leak.
Note for stable backports: the file to patch in versions <= 5.3 is
fs/btrfs/extent-tree.c
Fixes: 49303381f1 ("Btrfs: bail out if block group has different mixed flag")

I noticed when folding the trace_btrfs_space_reservation() tracepoint
into the btrfs_space_info_update_* helpers that we didn't emit a
tracepoint when doing btrfs_add_reserved_bytes(). I know this is
because we were swapping bytes_may_use for bytes_reserved, so in my mind
there was no reason to have the tracepoint there. But now there is
because we always emit the unreserve for the bytes_may_use side, and
this would have broken if compression was on anyway. Add a tracepoint
to cover the bytes_reserved counter so the math still comes out right.

We duplicate this tracepoint everywhere we call these helpers, so update
the helper to have the tracepoint as well.

btrfs_calc_trunc_metadata_size differs from trans_metadata_size in that
it doesn't take into account any splitting at the levels, because
truncate will never split nodes. However truncate _and_ changing will
never split nodes, so rename btrfs_calc_trunc_metadata_size to
btrfs_calc_metadata_size. Also btrfs_calc_trans_metadata_size is purely
for inserting items, so rename this to btrfs_calc_insert_metadata_size.
Making these clearer will help when I start using them differently in
upcoming patches.

These were renamed and exported to facilitate logical migration of
different code chunks into block-group.c. Now that all the users are in
one file go ahead and rename them back, move the code around, and make
them static.
