Jeremy Kerr d219889b76 powerpc/spufs: Check file offset before calculating write size in fixed-sized files 
Based on an original patch from Roel Kluin <roel.kluin@gmail.com>.

The write size calculated during regs and fpcr writes may currently
go negative. Because size is unsigned, this will wrap, and our
check for EFBIG will fail.

Instead, do the check for EFBIG before subtracting from size.
