intel/fs: Don't allocate a param array for zero push constants

Thanks to the ralloc invariant of "any pointer returned from ralloc can
be used as a context", calling ralloc_size with a size of zero will
cause it to allocate at least a header.  If we don't have any push
constants, then NULL is perfectly acceptable (and even preferred).
