f2fs: fix to active page in lru list for read path

Browse source 
If config CONFIG_F2FS_FAULT_INJECTION is on, for both read or write path
we will call find_lock_page() to get the page, but for read path, it
missed to passing FGP_ACCESSED to allocator to active the page in LRU
list, result in being reclaimed in advance incorrectly, fix it.
