If the mmap() call in rpc.statd fails, rpc.statd prints a warning

Browse Source 
message and then dumps core because the subsequent code assumes that
mmap() succeeded.  Since rpc.statd does not have fallback code to
implement the functionality needed to operate on the status file if
it is not memory mapped, rpc.statd should use err() to force the process
to exit if the mmap() call fails.
