drivers/spi/spi_flash.c: Avoid static scan false positive
Static scan-build indicates a possible invalid return from function
spi_flash_cmd_erase(). The root cause is because the scan believes it's
possible for offset to be above the end address in the first pass, thus
not setting a value for variable ret. Assign initial value of -1 to
variable ret to make checker happy.
