dda97e385b target/mips: Fix ADD.S FPU instruction
After merging latest QEMU upstream into our CHERI fork,
I noticed that some of the FPU tests in our MIPS baremetal
testsuite [*] started failing.
It turns out commit 1ace099f2a accidentally changed add.s
into a subtract.

Fixes: 1ace099f2a ("target/mips: fpu: Demacro ADD.<D|S|PS>")

9579f78168 target/mips: fpu: Refactor conversion from ieee to mips exception flags
The original coversion function is used for regular and MSA floating
point instructions handling. Since there are some nuanced differences
between regular and MSA floating point exception handling, provide two
instances of the conversion function, rather than just a single common
one. Inline both instances of this function instances for the sake of
performance. Improve variable naming in surrounding code for clarity.
