F2FS_BLKSIZE and 4096 are both used in f2fs_io for IO/buffer size, but F2FS_BLKSIZE may confuse user becasue it may be 4KB, 16KB, so use macro F2FS_DEFAULT_BLKSIZE to unify F2FS_BLKSIZE and 4096 in f2fs_io, also adjust "-c" parameters in mkfs man, to be consistent with commit c35fa8cd75ac ("mkfs.f2fs: change -c option description").
