Handle errors from spl_kern_path_locked()

Browse Source 
When the Linux 3.6 KERN_PATH_LOCKED compatibility code was added
by commit bcb1589 an entirely new vn_remove() implementation was
added.  That function did not properly handle an error from
spl_kern_path_locked() which would result in an panic.  This
patch addresses the issue by returning the error to the caller.
