Gaowei Pu ff68dac6d6 mm/mmap.c: use IS_ERR_VALUE to check return value of get_unmapped_area
get_unmapped_area() returns an address or -errno on failure.  Historically
we have checked for the failure by offset_in_page() which is correct but
quite hard to read.  Newer code started using IS_ERR_VALUE which is much
easier to read.  Convert remaining users of offset_in_page as well.
