Subject: [PATCH] loongarch/kgdb: use IS_ERR_PCPU() macro

In 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().
