mtd: spi-nor: remove WARN_ONCE() message in spi_nor_write()
This patch removes the WARN_ONCE() test in spi_nor_write(). This macro triggers the display of a warning message almost every time we use a UBI file-system because a write operation is performed at offset 64, which is in the middle of the SPI NOR memory page. This is a valid operation for ubifs. Hence this warning is pretty annoying and useless so we just remove it.
