pfinet: check MAP_FAILED immediately after mmap in S_pfinet_getroutes
The MAP_FAILED check for rtable was placed after get_routing_table
and memset had already dereferenced the pointer. If mmap failed
under memory pressure, pfinet would crash. Move the check to
immediately after mmap, release global_lock and return ENOMEM.
Also defer setting *dealloc_data until after confirming mmap
succeeded.
* pfinet/pfinet-ops.c (S_pfinet_getroutes): Check rtable for
MAP_FAILED right after mmap; set *dealloc_data only on success.

pfinet: add MAP_FAILED check after mmap in S_pfinet_siocgifconf
The mmap call to allocate a buffer for SIOCGIFCONF had no
MAP_FAILED check before the buffer was passed to dev_ifconf.
If mmap fails under memory pressure, pfinet would crash
writing to address (void *)-1.
* pfinet/pfinet-ops.c (S_pfinet_siocgifconf): Check ifc.ifc_buf
for MAP_FAILED immediately after mmap, release global_lock and
return ENOMEM on failure.
