gpu: nvgpu: fix use of untrusted scalar value
Kind value can be passed to API nvgpu_vm_map() from User
space (through IOCTL NVGPU_AS_IOCTL_MAP_BUFFER_EX)
But kind value is not checked for sane values
before storing it in bfr.kind_v
And then we use this kind value as array index
in gk20a_kind_is_supported() which is incorrect
Fix this by ensuring in nvgpu_vm_map() that the
kind value is well within range
