powerpc/ptrace: Split gpr32_set_common
objtool reports the following warning:
arch/powerpc/kernel/ptrace/ptrace-view.o: warning: objtool:
gpr32_set_common+0x23c (.text+0x860): redundant UACCESS disable
gpr32_set_common() conditionally opens and closes UACCESS based on
whether kbuf pointer is NULL or not. This is wackelig.
Split gpr32_set_common() in two fonctions, one for user one for
kernel.
