sb/intel/common: Use correct bitwise operator
Like the line above it, this should be & instead of | (otherwise it will
always incorrectly return true). spi_locked() is only used internally to
decide which opcodes will be used to talk to the flash, and if it is
falsely reported as locked, the worst case should be a denial of service
(unless there are more bugs).
