fs/nilfs2: Use the enum req_op and blk_opf_t types
Improve static type checking by using the enum req_op type for variables
that represent a request operation and the new blk_opf_t type for
variables that represent request flags. Combine the 'mode' and
'mode_flags' arguments of nilfs_btnode_submit_block into a single
argument 'opf'.
