Disable the -Wadress-of-packaed-member diagnostic for grub_utf8_to_utf16()
call which contains filep->path_name reference. It seems safe because the
structure is defined according to the UEFI spec and we hope authors did not
make any mistake... :-)
This fix is similar to the fix in the commit 8e8723a6b
(f2fs: Disable gcc9 -Waddress-of-packed-member).
