powerpc/booke: Fix breakpoint/watchpoint one-shot behavior
Another fix for the extended ptrace patches in the -next tree. The handling of breakpoints and watchpoints is inconsistent. When a breakpoint or watchpoint is hit, the interrupt handler is clearing the proper bits in the dbcr* registers, but leaving the dac* and iac* registers alone. The ptrace code to delete the break/watchpoints checks the dac* and iac* registers for zero to determine if they are enabled. Instead, they should check the dbcr* bits.
