Subject: [PATCH] grub_fs_probe(): dprint errors from filesystems
When filesystem detection fails, all that's currently debug-logged is a
series of messages like:
grub-core/kern/fs.c:56:fs: Detecting ntfs...
grub-core/kern/fs.c:76:fs: ntfs detection failed.
repeated for each filesystem. Any messages provided to grub_error() by
the filesystem are lost, and one has to break out gdb to figure out what
went wrong.
With this change, one instead sees:
grub-core/kern/fs.c:56:fs: Detecting fat...
grub-core/osdep/hostdisk.c:357:hostdisk: reusing open device
`/path/to/device'
grub-core/kern/fs.c:77:fs: error: invalid modification timestamp for /.
grub-core/kern/fs.c:79:fs: fat detection failed.
in the debug prints.

(cherry picked from commit 838c79d658797d0662ee7f9e033e38ee88059e02)
