drm/vkms: Fix cpu_to_le16()/le16_to_cpu() warnings

Browse Source 
Building with Sparse enabled prints this warning for cpu_to_le16()
calls:

    warning: incorrect type in assignment (different base types)
        expected unsigned short [usertype]
        got restricted __le16 [usertype]

And this warning for le16_to_cpu() calls:

    warning: cast to restricted __le16

Declare the target buffer as __le16 to fix both warnings.
