spidev: Decrease indentation level in spidev_ioctl() SPI_IOC_RD_MODE*

Browse Source 
Instead of defining a local controller variable inside an indented
block, move the definition to the top of spidev_ioctl() and reuse
it in the SPI_IOC_RD_MODE* and SPI_IOC_WR_MODE* cases.

This drops unneeded indentation and reduces amount of LoCs.
