[PATCH 1/4] Btrfs: cleanup: return the ret value of __btrfs_end_transaction directly in btrfs_end_transaction_

[Wang Sheng-Hui <shhuiw@gmail.com>]

No need to use specific var to record the return value of
__btrfs_end_transaction and check if it is not zero.
Just return the result directly as btrfs_end_transaction_dmeta.
