Michael Brown c9f6a86059 [efi] Fix uninitialised data in HII IFR structures
The HII IFR structures are allocated via realloc() rather than
zalloc(), and so are not automatically zeroed.  This results in the
presence of uninitialised and invalid data, causing crashes elsewhere
in the UEFI firmware.

Fix by explicitly zeroing the newly allocated portion of any IFR
structure in efi_ifr_op().
