For erofs_map_blocks() and erofs_map_blocks_flatmode(), the flags
argument is always EROFS_GET_BLOCKS_RAW. Thus remove the unused flags
parameter for these two functions.
Besides EROFS_GET_BLOCKS_RAW is originally introduced for reading
compressed (raw) data for compressed files. However it's never used
actually and let's remove it now.

Should we remove this in the next patch?
Otherwise it looks good to me.
