pony_spi.c: Fix memory leak in function pony_init_spi

I found the issue by running scan-build. Memory leaked was caused as
data variable wasn't deallocated in some error cases where the
function returned without deallocatiing it. After making the changes the
issue was no longer appeared in scan-build.
