target/mips: Fix msa checking condition in trans_msa_elm_fn()

Fix issue that condition of check_msa_enabled(ctx) is reversed
that causes segfault when msa elm_fn op encountered.

Fixes: 2f2745c81a ("target/mips: Convert MSA COPY_U opcode to decodetree")
Fixes: 97fe675519 ("target/mips: Convert MSA COPY_S and INSERT opcodes to decodetree")
