mtd: spi-nor-core: Invert logic to reflect sst26 flash unlocked

flash_is_locked is changed to flash_is_unlocked with commit 513c6071ce73
("mtd: spi: Convert is_locked callback to is_unlocked"). sst26_is_locked()
is also changed to sst26_is_unlocked() but the logic remained same.
Invert the logic for the flash lock/unlock to work properly.
