env: sf: Free the old env_flash
env_flash is a global flash pointer, and the probe would
happen only if env_flash is NULL, but there is no checking
and free the pointer if is not NULL.
So, this patch frees the old env_flash, and get the probed
flash in to env_flash pointer and finally check if is not NULL.
