ogg_afh_common: Fix signedness issue.

The previous patch introduced a regression because "granule" was made
unsigned by mistake but needs to be a signed variable. This can cause
the loop in oac_get_file_info() to not terminate which eventually
results in an abort due to an allocation failure:

	para_realloc: realloc failed (size = 2097152000), aborting
