[OE-core] [dora][PATCH 2/2] populate-extfs.sh: error out if debugfs encounters some error

[Chen Qi]

Previously, even if we encounter some error when populating the
ext filesystem, we don't error out and the rootfs process still
succeeds.

However, what's really expected is that the populate-extfs.sh script
should error out if something wrong happens when using `debugfs' to
generate the ext filesystem. For example, if there's not enough block
in the filesystem, and allocating a block for some file fails, the
failure should not be ignored. Otherwise, we will have a successful
build but a corrupted filesystem.

The debugfs returns 0 as long as the command is valid. That is, even
if the command fails, the debugfs still returns 0. That's really a
pain here. That's why this patch checks the error output to see whether
there's any error logged.
