In spi_flash.c, if CONFIG_SPI_FLASH_BAR is enabled, the function 'clean_bar' makes sure that the Bank Address Register is reset at the end of functions using it.
However, if this is enabled, those functions may return zero (success) when they should return an error. This is because after e.g. 'spi_flash_read_common' fails, the return value in 'ret' is overwritten with the return value of 'clean_bar'.
Fix this by changing 'clean_bar' to take the outer error code into account and returning its own return value only if the outer error code is 0.

This can be dropped due to Vignesh's series that updates SPI NOR.
