btrfs: Fix transaction abort during failure in btrfs_rm_dev_item
[ Upstream commit 5e9f2ad5b2904a7e81df6d9a3dbef29478952eac ] btrfs_rm_dev_item calls several function under an active transaction, however it fails to abort it if an error happens. Fix this by adding explicit btrfs_abort_transaction/btrfs_end_transaction calls.
