[TRIVIAL PATCH] Ensure pfn_to_nid() is always defined for i386

[Matthew Dobson]

pfn_to_nid() is defined for *almost* all configurations for i386.  There 
is a small bug in that for CONFIG_X86_PC it is not.  This just sets up a 
generic definition so that this function is always defined in a 
reasonable manner.

Cheers!
