ext4: remove pointless sb_rdonly() checks from freezing code
ext4_freeze() and ext4_unfreeze() checks for sb_rdonly(). However this check is pointless as VFS already checks for read-only filesystem before calling filesystem specific methods. Remove the pointless checks. Signed-off-by: Jan Kara <jack@suse.cz> Link: https://lore.kernel.org/r/20230616165109.21695-1-jack@suse.cz Signed-off-by: Theodore Ts'o <tytso@mit.edu>
