fuse: don't fill in.h.pid in case args->nocreds is set

Commit 794e811d1443 ("fuse: split out filesystem part of request sending")
alters the pid sent on force && nocreds requests.

Previously these allocated a zeroed request and skipped fuse_force_creds(),
so they went out with in.h.pid == 0.

In fuse_fill_creds(), args->pid is now set before the nocreds early return,
and fuse_args_to_req() copies it unconditionally - so writeback, release,
and DESTROY requests now report the triggering (often kernel-worker) pid
instead of 0.

Move the nocreds check above setting args->pid.  Also remove the
WARN_ON(!args->nocreds) from the !args->force branch, since it's obviously
not going to be triggered.
