There are some cases of f2fs_is_valid_blkaddr not handled as
ERROR_INVALID_BLKADDR,so unify the error handling about all of
f2fs_is_valid_blkaddr.
Do f2fs_handle_error in __f2fs_is_valid_blkaddr for cleanup.

v8: do reboot/monkey stability test for this version and result pass.
do f2fs_handle_error in __is_bitmap_valid for resolving the
ugly code problem mentioned by Jaegeuk, besides handle the situation
of “type == DATA_GENERIC_ENHANCE_UPDATE” reasonably.
