Subject: [PATCH v2 1/6] powerpc/fadump: rename cpu_online_mask member of struct fadump_crash_info_header

As preparation for eliminating the indirect access to the various
global cpu_*_bits bitmaps via the pointer variables cpu_*_mask, rename
the cpu_online_mask member of struct fadump_crash_info_header to
simply online_mask, thus allowing cpu_online_mask to become a macro.
