The return error check on the call to ath11k_pci_get_user_msi_assignment is
missing. If an error does occur, num_vectors is still set to zero and
later on a division by zero can occur when variable vector is being
calculated. Fix this by adding an error check after the call.
Addresses-Coverity: ("Division or modulo by zero")
Fixes: d4ecb90b3857 ("ath11k: enable DP interrupt setup for QCA6390")
