rtlwifi: rtl8188ee: rtl8723ae: rtl8821ae: Initialize some variables

In a number of places, kmalloc or valloc were used to acquire memory.
To ensure that these locations are correctly initialized, the calls were
changed to kzalloc and vzalloc. The change fixes a problem that was causing
HT operations to be cancelled.
