rtw88: extract alloc rsvd_page and h2c skb routines
Extract skb allocation routines for rsvd_page and h2c.
These routines should also be used by USB and SDIO.
This should not change the logic at all.
memset() for pkt_info is unnecessary, just declare as {0}.
Also skb_put()/memcpy() can be replaced by skb_put_data().
