[PATCH 5.8 055/232] media: venus: fix multiple encoder crash

[Greg Kroah-Hartman]

From: Mansur Alisha Shaik <mansur@xxxxxxxxxxxxxx>

commit e0eb34810113dbbf1ace57440cf48d514312a373 upstream.

Currently we are considering the instances which are available
in core->inst list for load calculation in min_loaded_core()
function, but this is incorrect because by the time we call
decide_core() for second instance, the third instance not
filled yet codec_freq_data pointer.

Solve this by considering the instances whose session has started.
