block: Cleanup set_capacity()/bdev_set_nr_sectors()
The code for setting a block device capacity (bd_nr_sectors field of
struct block_device) is duplicated in set_capacity() and
bdev_set_nr_sectors(). Clean this up by making bdev_set_nr_sectors()
a block layer internal function defined in block/bdev.c instead of
having this function statically defined in block/partitions/core.c.
With this change, set_capacity() implementation can be simplified to
only calling bdev_set_nr_sectors().
