rsi: Use resume_noirq for SDIO
The rsi_resume() does access the bus to enable interrupts on the RSI
SDIO WiFi card, however when calling sdio_claim_host() in the resume
path, it is possible the bus is already claimed and sdio_claim_host()
spins indefinitelly. Enable the SDIO card interrupts in resume_noirq
instead to prevent anything else from claiming the SDIO bus first.
Fixes: 20db07332736 ("rsi: sdio suspend and resume support")
