target/loongarch: Fix LD/ST{LE/GT} instructions get wrong CSR_ERA and CSR_BADV 
1.helper_asrtle_d/helper_asrtgt_d need use GETPC() to get PC;
2 LD/ST{LE/GT} need set CSR_BADV = gpr[rj];
3 ASRTLE.D/ASRTGT.D also write CSR_BADV, but this value is random
  and has no reference value.

064357041d target/loongarch/op_helper: Fix coverity cond_at_most error 
The boundary size of cpucfg array should be 0 to ARRAY_SIZE(cpucfg)-1.
So, using index bigger than max boundary to access cpucfg[] must be
forbidden.

Fix coverity CID: 1489760
