Subject: btrfs: stop using block_rsv_release_bytes everywhere
Git-commit: 424a47805a819ff59ada9549c4a21fe0ba95c446
Patch-mainline: v5.3-rc1
References: bsc#1165949

block_rsv_release_bytes() is the internal to the block_rsv code, and
shouldn't be called directly by anything else.  Switch all users to the
exported helpers.
