rsmp: fix segment fault in rsmp
rsmp: fix segment fault in rsmp

The existing code takes wrong field in 32 bit entry
table for total struct table length that specifies
the length of memory for mmap(). When actual mmap
length is smaller than the actual table size, rsmp
walks into area not mapped. The result is a segment
fault.
