Remove a redundant call to amdgpu_ctx_priority_is_valid() from
amdgpu_ctx_priority_permit(), which is called from amdgpu_ctx_init() which is
called from amdgpu_ctx_alloc() which is called from amdgpu_ctx_ioctl(), where
we've called amdgpu_ctx_priority_is_valid() already first thing in the
function.
