f2fs: cleanup the f2fs_bio_alloc routine
Do cleanup more for better code readability. - Change the parameter set of f2fs_bio_alloc() This function should allocate a bio only since it is not something like f2fs_bio_init(). Instead, the caller should initialize the allocated bio. - Introduce SECTOR_FROM_BLOCK This macro translates a block address to its sector address.
