powerpc/xmon: Fiddle xmon_depth_to_print logic in xmon_show_stack()
Currently xmon_depth_to_print is static and global, but it's only ever used in xmon_show_stack(). At least with a modern compiler it's inlined, so there's no point in it being static, we could #define it but it's only used in one place. By reworking the logic we can drop count and just decrement the max value as a loop counter. Also switch to a while loop so we actually print no more than 64 frames as you'd expect based on the variable name.
