drm/amdgpu: simplify return value in amdgpu_userq_get_doorbell_index

Browse Source 
amdgpu_userq_get_doorbell_index returns a uint64 type index
as well as a int type failure values. Simplifying this and
using a int type return value and getting the index in input pointer
of type uint64 type.

Also since it's used at once place making it static would be better.
