ubi: Add a check for ubi_num
Added a check for ubi_num for negative numbers
If the variable ubi_num takes negative values then we get:
qemu-system-arm ... -append "ubi.mtd=0,0,0,-22222345" ...
[ 0.745065] ubi_attach_mtd_dev from ubi_init+0x178/0x218
[ 0.745230] ubi_init from do_one_initcall+0x70/0x1ac
[ 0.745344] do_one_initcall from kernel_init_freeable+0x198/0x224
[ 0.745474] kernel_init_freeable from kernel_init+0x18/0x134
[ 0.745600] kernel_init from ret_from_fork+0x14/0x28
[ 0.745727] Exception stack(0x90015fb0 to 0x90015ff8)
Found by Linux Verification Center (linuxtesting.org) with SVACE.
