grub: don't print messages if a module isn't found
it can annoy some users, so just silence it. we don't need a lot of modules so we only have a few, but some distro grub configs can load modules frivilously. Signed-off-by: Leah Rowe <leah@libreboot.org>

+Subject: [PATCH 1/1] don't print error if module not found
+
+still set grub_errno accordingly, and otherwise
+behave the same. in libreboot, we remove a lot of
+modules but then rely on loading a grub.cfg
+provided by a distro; in almost all cases that works,
+but also in almost all cases, that will try to load
+a module we don't actually need, but then it prints
+a message. this can annoy some users, so silence it.
