raid5: separate header for log functions
Move raid5-cache declarations from raid5.h to raid5-log.h, add inline
wrappers for functions which will be shared with ppl and use them in
raid5 core instead of direct calls to raid5-cache.
Remove unused parameter from r5c_cache_data(), move two duplicated
pr_debug() calls to r5l_init_log().
