FS-Cache: Avoid maybe-used-uninitialised warning on variable

Andrew Morton's compiler sees the following warning in FS-Cache:

fs/fscache/object-list.c: In function 'fscache_objlist_lookup':
fs/fscache/object-list.c:94: warning: 'obj' may be used uninitialized in this function

which my compiler doesn't.  This is a false positive as obj can only be
used in the comparison against minobj if minobj has been set to something
other than NULL, but for that to happen, obj has to be first set to
something.

Deal with this by preclearing obj too.
