[committed] fix thinko in frv_initial_elimination_offset

[Richard Sandiford]

This patch fixes the sign of the frv fp -> sp elimination offset.
The code in question is effectively dead since we should always
be using a frame pointer whenever we need a frame.  But I noticed
it while making some local changes.

Tested on frv-elf & committed as obviously correct.
