The goal of a bank is to make as much money as it can with it's assets. It's in the banks interest to loan out as much as it safely can while staying above the reserve requirements. If a bank were to dump it's assets to ensure it met reserve requirements it would likely sell at firesale prices which could drive down the price of those assets for the rest of the market. By taking a loan from the Fed and using those assets as collateral that scenario is avoided. It's also worth noting that these loans are not free, the Fed does charge interest.
So the bank avoids dipping below reserve requirements (and flooding the asset market) and the Fed earns a small amount of interest.
