Fix bug that would result in a kernel crash in some cases involving
a symlink and an autofs mount request.  The crash was caused by namei()
calling bcopy() with a negative length, caused by numeric underflow:
in lookup(), in the relookup path, the ni_pathlen was decremented too
many times.  The bug was introduced in r296715.

Big thanks to Alex Deiter for his help with debugging this.
