f2fs: add unlikely() macro for compiler more aggressively
This patch adds unlikely() macro into the most of codes. The basic rule is to add that when: - checking unusual errors, - checking page mappings, - and the other unlikely conditions. Change log from v1: - Don't add unlikely for the NULL test and error test: advised by Andi Kleen.
