In e820_finalize(), the e820_fwcfg_item variable, containing the etc/e820 file (for the e820 table from the BIOS) is not free()'d when it could not be added to the QEMU firmware configuration device (fw_cfg).

Source code review.

The only user of this function I could find is bhyve_init_platform_late(), which is called by main() in bhyverun.c, which exits upon errors. (4 "exited due to an error")

Therefore, as things are this fix looks superfluous, but it would quiet Coverity down for this code path.
