perf/hw_breakpoint: use ERR_PTR_PCPU(), IS_ERR_PCPU() and PTR_ERR_PCPU() macros

Use ERR_PTR_PCPU() when returning error pointer in the percpu address
space.  Use IS_ERR_PCPU() and PTR_ERR_PCPU() when returning the error
pointer from the percpu address space.  These macros add intermediate cast
to unsigned long when switching named address spaces.

The patch will avoid future build errors due to pointer address space
mismatch with enabled strict percpu address space checks.
