[PATCH] fs: ramfs: simplify len calculation in ramfs_find_chunk

[Ahmad Fatoum]

ramfs_find_chunk finds the correct chunk and additionally returns via
argument pointers the offset to use and the remaining length.

While correct, the way the remaining len is calculated can be simplified
by using the offset previously calculated:

  data->ofs  +        data->size - pos
  data->size -  pos + data->ofs
  data->size - (pos - data->ofs)
  data->size - (*ofs)

Do that for clarity. No functional change.
