cifs: fix check of error return from is_path_accessable 

This function will return 0 if everything went ok. Commit 9d002df4
however added a block of code after the following check for
rc == -EREMOTE. With that change and when rc == 0, doing the
"goto mount_fail_check" here skips that code, leaving the tlink_tree
and master_tlink pointer unpopulated. That causes an oops later
in cifs_root_iget.
