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