err.h: add ERR_PTR_PCPU(), PTR_ERR_PCPU() and IS_ERR_PCPU() macros
Add ERR_PTR_PCPU(), PTR_ERR_PCPU() and IS_ERR_PCPU() macros that operate
on pointers in the percpu address space.
These macros remove the need for (__force void *) function argument casts
(to avoid sparse -Wcast-from-as warnings).
The patch will also avoid future build errors due to pointer address space
mismatch with enabled strict percpu address space checks.
