ext4: report real fs size after failed resize
[ Upstream commit 6c7328400e0488f7d49e19e02290ba343b6811b2 ]
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 a warning that "error occurred during file system
resize"
