[Patch] MdeModulePkg/LogoDxe: Return error if HII Package not present

[Michael Kinney <michael.d.kinney@intel.com>]

https://bugzilla.tianocore.org/show_bug.cgi?id=554

Update LogoDxe module to exit with an error instead of
ASSERT_EFI_ERROR() if the HII Package with the logo image
is not present.

If a tool chain does not support generation of PE/COFF
resource sections, then this module can not produce the logo
from an HII Image Package.  XCODE5 is an example of a tool
chain that does not currently support generation of PE/COFF
resource sections.
