target/mips: Simplify MSA TCG logic
Only decode MSA opcodes if MSA is present (implemented).
Now than check_msa_access() will only be called if MSA is
present, the only way to have MIPS_HFLAG_MSA unset is if
MSA is disabled (bit CP0C5_MSAEn cleared, see previous
commit). Therefore we can remove the 'reserved instruction'
exception.
