accel/amdxdna: Remove hardware context status

accel/amdxdna: Remove hardware context status

One newly supported command does not require hardware context configuration
to be performed upfront. As a result, checking hardware context status
causes this command to fail incorrectly.

Remove hardware context status handling entirely. For other commands,
if userspace submits a request without configuring the hardware context
first, the firmware will report an error or time out as appropriate.
