net: atlantic: Avoid out-of-bounds indexing
UBSAN warnings are observed on atlantic driver:
[ 294.432996] UBSAN: array-index-out-of-bounds in /build/linux-Qow4fL/linux-5.15.0/drivers/net/ethernet/aquantia/atlantic/aq_nic.c:484:48
[ 294.433695] index 8 is out of range for type 'aq_vec_s *[8]'
The ring is dereferenced right before breaking out the loop, to prevent
that from happening, only use the index in the loop to fix the issue.
