[PATCH 3/8] md: widen badblock sectors param from int to sector_t

[Hiroshi Nishida <nishidafmly@gmail.com>]

The badblocks core API -- badblocks_set(), badblocks_clear() and
badblocks_check() -- and the is_badblock() helper all take the range
length as sector_t.  The md wrappers rdev_set_badblocks(),
rdev_clear_badblocks() and rdev_has_badblock(), however, declared the
same length as int, narrowing sector_t to int and back again in the
middle of an otherwise 64-bit clean path.

Change the sectors parameter to sector_t in these three wrappers so it
matches the core API and is_badblock().  No functional change: current
callers pass per-I/O or per-resync-chunk lengths well within int range.
This just removes a gratuitous truncation point and keeps the type
consistent end to end.
