MIPS: Actually decode JALX in `__compute_return_epc_for_insn'

commit a9db101b upstream.

Complement commit fb6883e5 ("MIPS: microMIPS: Support handling of
delay slots.") and actually decode the regular MIPS JALX major
instruction opcode, the handling of which has been added with the said
commit for EPC calculation in `__compute_return_epc_for_insn'.

Fixes: fb6883e5 ("MIPS: microMIPS: Support handling of delay slots.")
