qcacld-3.0: Use vtable for rx blocksize

Browse Source 
One of the HDD functions with the highest cyclomatic complexity is
__wlan_hdd_cfg80211_wifi_configuration_set(). In order to reduce the
complexity there is a plan to replace the inline attribute handling
with a vtable-based approach.

As part of that goal update the signature of the following function
and add that function to the vtable:
- wlan_hdd_cfg80211_wifi_set_rx_blocksize()

Note that with this change all of the attribute handling in
__wlan_hdd_cfg80211_wifi_configuration_set() has been relocated to the
vtables. The measured cyclematic complexity was reduced from 103 to 6.
