spi: rpc-if: Use correct device for hardware reinitialization on resume

Browse Source 
rpcif_spi_resume() currently passes the SPI controller device to
rpcif_hw_init(), but the function should be called with the RPC
interface device.

Retrieve the rpcif private data from the SPI controller and pass
rpc->dev instead. Also propagate the return value of rpcif_hw_init() so
that a failure during resume is properly reported rather than silently
ignored.
