target/m68k: fix FPSR quotient byte for frem instruction
The FPSR quotient byte should be set to the value of the quotient and not the
result. Manually calculate the quotient in the frem helper in round to nearest
even mode (note this is different from the quotient calculated internally for
fmod), and use it to set the quotient byte accordingly.
