bcrmgf_netif_rx() uses in_interrupt to chose between netif_rx() and
netif_rx_ni(). in_interrupt() usage in drivers is phased out.
Convey the execution mode via an 'inirq' argument through the various
callchains leading to brcmf_netif_rx():
brcmf_pcie_isr_thread() <- Task context
brcmf_proto_msgbuf_rx_trigger()
brcmf_msgbuf_process_rx()
brcmf_msgbuf_process_msgtype()
brcmf_msgbuf_process_rx_complete()
brcmf_netif_mon_rx()
brcmf_netif_rx(isirq = false)
brcmf_netif_rx(isirq = false)
brcmf_sdio_readframes() <- Task context sdio_claim_host() might sleep
brcmf_rx_frame(isirq = false)
brcmf_sdio_rxglom() <- Task context sdio_claim_host() might sleep
brcmf_rx_frame(isirq = false)
brcmf_usb_rx_complete() <- Interrupt context
brcmf_rx_frame(isirq = true)
brcmf_rx_frame()
brcmf_proto_rxreorder()
brcmf_proto_bcdc_rxreorder()
brcmf_fws_rxreorder()
brcmf_netif_rx()
brcmf_netif_rx()
