Subject: [PATCH 2/5] venus: hfi_parser: Check for instance after hfi platform get

The inst function argument is != NULL only for Venus v1 and
we did not migrate v1 to a hfi_platform abstraction yet. So
check for instance != NULL only after hfi_platform_get returns
no error.

Fixes: e29929266be1 ("media: venus: Get codecs and capabilities from hfi platform")
Cc: stable@...r.kernel.org # v5.12+
