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().
