[PATCH] media: venus: venus_helper_get_bufreq(): req is never NULL

[Hans Verkuil <hverkuil@xxxxxxxxx>]

Fix a smatch error:

drivers/media/platform/qcom/venus/helpers.c: drivers/media/platform/qcom/venus/helpers.c:678 venus_helper_get_bufreq() error: we previously assumed 'req' could be null (see line 674)

After checking how venus_helper_get_bufreq() is called it is clear that
req is never NULL, so just drop the check.
