[PATCH] lib: fwts_coreboot_cbmem: fix cbmem_console_addr check

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The check to see if parse_cbmem_ref returned non-zero should
be checking the contents of cbmem_console_addr and not
the pointer cbmem_console_addr. Add the missing *.

Detected by CoverityScan, CID#1394471 ("Dereference before null check")

Fixes: c9bf07f25d13 ("fwts_coreboot.c: add cbmem console parser")
