The only function called through this pointer type doesn't return
a value and the caller doesn't check for a return value. Change
the function pointer type to return void to fix a CFI failure due
to a type mismatch:
CFI failure (target: [<ffffff853ba7cee8>]
hdd_ipa_send_skb_to_network+0x0/0x4 [wlan]):
...
Call trace:
__ubsan_handle_cfi_check_fail+0x50/0x58
__cfi_check+0x31fa0/0x3d5a4 [wlan]
wlan_ipa_w2i_cb+0x5fc/0x8fc [wlan]
