[PATCH u-boot-spi v3 06/10] mtd: spi-nor-core: Don't check for zero length in spi_nor_write() / spi_nor_erase()

["Marek Behún" <kabel@kernel.org>]

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

This check is already done in all callers: mtdcore's mtd_write() /
mtd_erase(), legacy spi_nor_write() / spi_flash_erase(). No reason to do
this here as well.

Signed-off-by: Marek Behún <marek.behun@nic.cz>

Changes since v2:
- remove check for zero length also from spi_nor_write()
