env: sf: fix environment in SPI NOR
commit 9a9d66f5eff0 ("env: add spi_flash_read_env function") breaks Environment functionality, as it reads only until 2 \0 are found, but fills the buffer with 0x0 instead 0xff which leads in an incorrect crc sum. Fix: init the read buffer with 0xff instead 0x00 Signed-off-by: Heiko Schocher <hs@denx.de>
