anv: Fix calculation of syncs required in Xe KMD

Browse Source 
num_syncs was being incremented by one if 'utrace_submit != NULL' but
a sync was only being set if also
'util_dynarray_num_elements(&utrace_submit->batch_bos) == 0'.

This mismatch could cause application to abort due to
'assert(count == num_syncs)'.
