LoongArch: Use IS_ERR_PCPU() macro for KGDB

In commit a759e37fb467 ("err.h: add ERR_PTR_PCPU(), PTR_ERR_PCPU() and
IS_ERR_PCPU() macros"), specialized macros were added to check an error
within a __percpu pointer, so use them instead of manually casting with
__force, like all other users of register_wide_hw_breakpoint().
