[PATCH v2 2/2] ext4: Report real fs size after failed resize

[Lukas Czerner <lczerner@redhat.com>]

Currently when the file system resize using ext4_resize_fs() fails it
will report into log that "resized filesystem to <requested block
count>". However this may not be true in the case of failure. Use the
current block count as returned by ext4_blocks_count() to report the
block count.
Additionally report to log that "error occurred during file system
resize"
