[PATCH u-boot-spi v2 3/9] mtd: spi-nor-core: Don't overwrite return value if it is non-zero

["Marek Behún" <kabel@kernel.org>]

From: Marek Behún <marek.behun@nic.cz>

The cleanup code of the spi_nor_erase() function overwrites the ret
variable with return value of clean_bar(), even if the ret variable is
already set. Fix this.
