samples: bluetooth: iso_receive: Allow syncing any subevent number

When using softdevice controller on iso_broadcast sample, the BIG
created uses more than 1 subevent. This means that when you try to
use the iso_receive sample to sync it does not work.

So update the sample to use mse=0 and allow any number of subevents,
making the sample more flexible and work with SDC without any changes.
