s390x: free tmp explicitly in every opcode for disas_a5()
The disas_a5() function provided a TCG tmp variable which was populated
by the respective opcode implementations, but freed at the end of the
function in generic code.
That makes it really hard for code review, so let's move the freeing
to the same scope as the actual allocation.
