[libvirt] [PATCH] locking: remove redundant codes

[ajia redhat com]

From: Alex Jia <ajia redhat com>

* src/locking/lock_driver_sanlock.c: remove redundant codes in error_unlink 
  label from virLockManagerSanlockSetupLockspace, in fact, the codes make 
  sure 'path' is non-null before getting to error_unlink label, so 'if (path)'
  is redundant, removing it in here and will also silence coverity.
