Subject: [PATCH v1] realtek/rtlwifi: ensure unicast is reinitialized to false
 in each iteration

Previously, the unicast variable was only initialized once during the function execution. Therefore, if unicast was set to true in the (n-1)th iteration, it would affect the nth iteration. This patch resolves the issue by reinitializing unicast to false at the start of each iteration.
