Make GCPAGs_perproc_func cleaner for FBSD case
Partially rewrite
2cf1f10a to reduce code clutter.
Instead of accessing pproc->p_ucred directly in afs_GCPAGs_perproc_func(),
push this access into a FBSD-specific afs_proc2cred() function.
This is not quite right, since we do not lock the proc mutex, but
in the same way as the old version and with more reasonable preprocessor
conditionals.
This also eliminates a probably-needless call to osi_Panic.
