Josef Bacik 844245b454 btrfs: add a flush step for delayed iputs
Delayed iputs could very well free up enough space without needing to
commit the transaction, so make this step it's own step.  This will
allow us to skip the step for evictions in a later patch.

Goldwyn Rodrigues 9b4851bc48 btrfs: Simplify update of space_info in __reserve_metadata_bytes()
We don't need an if-else-if chain where we can use a simple OR since
both conditions are performing the same action. The short-circuit for OR
will ensure that if the first condition is true, can_overcommit() is not
called.

We'll need this exported so we can use it in all the various was we need
to use it.  This is prep work to move reserve_metadata_bytes.

These are the basic init and lookup functions and some helper functions,
fairly straightforward before the bad stuff starts.
