[ Upstream commit 42b530581f7246b3143ee50e3c6f981dcbb1dc74 ]

Grub would report an error message in boot stage as below:

   "error: no such device: ((hd0,gpt1)/EFI/BOOT)/EFI/BOOT/grub.cfg"

Consequently, the root variable is not set, and the intended protection
against cross-device configuration loading (the purpose of the original 2014 commit)
is lost.

The most robust fix is to use the --hint parameter.
This separates the search target from the device hint, avoiding
fragile string concatenation and supporting both prefixed and
non-prefixed $cmdpath formats.
