drm/amdgpu: Remove in_interrupt() usage in gfx_v9_0_kiq_read_clock()

Browse Source 
gfx_v9_0_get_gpu_clock_counter() acquires a mutex_t lock and is the only
caller of gfx_v9_0_kiq_read_clock().
If it safe to acquire a mutex_t then gfx_v9_0_get_gpu_clock_counter() is
always invoked from preemptible context.

Remove in_interrupt() because it superfluous as it will always return
false.
