spi: bcm63xx: return error from failed controller suspend

Browse Source 
spi_controller_suspend() can fail if the SPI core cannot stop the
controller. bcm63xx_spi_suspend() ignored that error, disabled the
controller clock, and returned success.

Return the suspend error before tearing down the clock.
