From: Su Yue <glass.su@xxxxxxxx>
mkfs.bcachefs now supports option '--block_size' to allow
custom block_size.
Add the pattern to set def_blksz if MKFS_OPTIONS contains the
option in _scratch_mkfs_sized.
Also let mkfs.bcachefs decide blocksize if no option is given in
MKFS_OPTIONS or _scratch_mkfs_sized parameter.
