spi: bcm-qspi: return error from failed controller suspend

Browse source

spi_controller_suspend() can fail if the SPI core cannot stop the
controller. bcm_qspi_suspend() ignored that error, disabled the
controller clock, uninitialized the hardware, and returned success.

Return the suspend error before tearing down the clock and hardware
state.
