drm/amd/display: Drop uncessary OTG lock check

Browse Source 
The OTG_MASTER_UPDATE_LOCK_SEL is used for GSL and OTGs in the same
group for selecting the OTG_MASTER_UPDATE_LOCK from the same OTG. At
some point, it a check was added to see if OTG is running or not, which
is not necessary, and for this reason, this commit dropped that check.
