Franky Lin 31143e2933 brcmfmac: add eth_type_trans back for PCIe full dongle
A regression was introduced in commit 9c349892cc ("brcmfmac: revise
handling events in receive path") which moves eth_type_trans() call
to brcmf_rx_frame(). Msgbuf layer doesn't use brcmf_rx_frame() but invokes
brcmf_netif_rx() directly. In such case the Ethernet header was not
stripped out resulting in null pointer dereference in the networking
stack.

BUG: unable to handle kernel NULL pointer dereference at 0000000000000048
