target/ppc: Ensure stcx size matches larx
Differently-sized larx/stcx. pairs can succeed if the starting address
matches. Add a check to require the size of stcx. exactly match the larx
that established the reservation. Use the term "reserve_length" for this
state, which matches the terminology used in the ISA.
