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"
