i86xpv/unix: 'rsdp' may be used uninitialized in this function
Build error with gcc 9:
../../i86pc/os/fakebop.c: In function 'build_firmware_properties': ../../i86pc/os/fakebop.c:2932:8: error: 'rsdp' may be used uninitialized in this function [-Werror=maybe-uninitialized] 2932 | tp = find_fw_table(rsdp, ACPI_SIG_MCFG); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors
Testing done: build/install (I only do have i86pc).
Indeed, we are missing call to find_rsdp().
