The function bio_trim has offset and size arguments that are declared
as int.

The callers of this function use sector_t type when passing the offset
and size, e.g. drivers/md/raid1.c:narrow_write_error() and
drivers/md/raid1.c:narrow_write_error().

Change offset and size arguments to sector_t type for bio_trim(). Also,
add WARN_ON_ONCE() to catch their overflow.
