powerpc/8xx: Fix warning in hw_breakpoint_handler() 



In hw_breakpoint_handler(), ea is set by wp_get_instr_detail() except
for 8xx, leading the variable to be passed uninitialised to
wp_check_constraints().  This is safe as wp_check_constraints() returns
early without using ea, so just set it to make the compiler happy.
