[PATCH 6/6] btrfs: cleanup btrfs_setxattr_trans drop trans arg

[Anand Jain <anand.jain@oracle.com>]

The previous preparatory
  btrfs: split thread with trans to use btrfs_setxattr
made sure that btrfs_setxattr_trans() is called only when trans arg is
NULL.

Now this patch cleanups btrfs_setxattr_trans() and drops the trans arg.
