Zhong Jinghua 4181c30a2c nbd: Add the maximum limit of allocated index in nbd_dev_add 
[ Upstream commit f12bc113ce904777fd6ca003b473b427782b3dde ]

If the index allocated by idr_alloc greater than MINORMASK >> part_shift,
the device number will overflow, resulting in failure to create a block
device.

Fix it by imiting the size of the max allocation.
