Subject: btrfs: call btrfs_try_granting_tickets when freeing reserved bytes
Git-commit: 3308234a7e9828f8cbec308010348ddf712fc15e
Patch-mainline: v5.10-rc1
References: bsc#1135481
We were missing a call to btrfs_try_granting_tickets in
btrfs_free_reserved_bytes, so add it to handle the case where we're able
to satisfy an allocation because we've freed a pending reservation.
