qcacmn: Fix band info update issue in error case

Currently during error process band is updated if txrx_peer is valid.
but in current logic txrx_peer was retrieved later which will always
result in condition failure and will cause band not to be update.

To fix the issue move getting txrx_peer part before band update.
