[PATCH] Fix wp-replication.exp for targets that provide only 1 hw watchpoint

[Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com>]

(sorry, my previous message got truncated. Resending...)

Hi,

current wp-replication.exp testcase counts 2 hw watchpoints even when the target
provides only 1 hw watch, resulting in several unexpected errors. Successfully
tested on x86 (with 4 hw watchpoints available) and ppc64 server (with 1 hw
watch), this patch intends to fix this issue. Ok?

Thanks,
