target/sparc: don't set FSR_NVA when comparing unordered floats

Browse source 
FSR_NVA should be set when one of the operands is a signaling NaN or
when using FCMPEx instructions. But those cases are already handled
within check_ieee_exception or floatxx_compare functions.
Otherwise, it should be left untouched.

FTR, this was detected by inf-compare-[5678] tests within gcc
testsuites.
