qcacld-3.0: Fix incorrect condition in sap_add_mac_to_acl function

Currently sap_add_mac_to_acl() function has incorrect validation check,
size of MacList will be always zero if no elements added to the list.

Validating size always be greater than zero will prevent adding first
element itself. There by breaking whole ACL functionality.

To fix this, remove ‘*size == 0’ condition in validation code.
