Fix zfs_rmnode() unlink / rollback issue
If a has rollback has occurred while a file is open and unlinked.
Then when the file is closed post rollback it will not exist in the
rolled back version of the unlinked object. Therefore, the call to
zap_remove_int() may correctly return ENOENT and should be allowed.
