[PATCH 1/1] efi_loader: fix efi_show_tables()

[Heinrich Schuchardt]

Since commit 041840eeeb12 ("efi: Split out table-listing code into a new
file") the `efi tables` command prints random numbers instead of GUIDs.
%pUl expects a pointer to a GUID not to a string.

Set maintainer for file cmd/efi_comon.c.
