block: add check of 'minors' and 'first_minor' in device_add_disk()

[ Upstream commit 4c434392c4777881d01beada6701eff8c76b43fe ]

'first_minor' represents the starting minor number of disks, and
'minors' represents the number of partitions in the device. Neither
of them can be greater than MINORMASK + 1.

Commit e338924bd05d ("block: check minor range in device_add_disk()")
only added the check of 'first_minor + minors'. However, their sum might
be less than MINORMASK but their values are wrong. Complete the checks now.
