Hagar HemdanandGreg Kroah-Hartman b8938d6f57 efi: libstub: only free priv.runtime_map when allocated ...

commit 4b2543f7e1 upstream.

priv.runtime_map is only allocated when efi_novamap is not set.
Otherwise, it is an uninitialized value.  In the error path, it is freed
unconditionally.  Avoid passing an uninitialized value to free_pool.
Free priv.runtime_map only when it was allocated.

This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.
