http.c: Drop useless != NULL test in finish_http_pack_request
http.c: Drop useless != NULL test in finish_http_pack_request

The test preq->packfile != NULL is always true.  If packfile was
actually NULL when entering this function the ftell() above would
crash out with a SIGSEGV, resulting in never reaching this point.

Simplify the code by just removing the conditional.
