vmcore: fix address space sparse warnings
Fix the following sparse warnings:
fs/proc/vmcore.c:173:34: sparse: incorrect type in argument 1
(different address spaces)
fs/proc/vmcore.c:173:34: expected void [noderef] <asn:1>*dst
fs/proc/vmcore.c:173:34: got void *target
fs/proc/vmcore.c:256:30: sparse: incorrect type in argument 1
(different address spaces)
fs/proc/vmcore.c:256:30: expected char *[assigned] buffer
fs/proc/vmcore.c:256:30: got char [noderef] <asn:1>*buffer
