Dan Carpenter c92eb06603 ext2: fix sleeping in atomic bugs on error 
[ Upstream commit 372d1f3e1bfede719864d0d1fbf3146b1e638c88 ]

The ext2_error() function syncs the filesystem so it sleeps.  The caller
is holding a spinlock so it's not allowed to sleep.

   ext2_statfs() <- disables preempt
   -> ext2_count_free_blocks()
      -> ext2_get_group_desc()

Fix this by using WARN() to print an error message and a stack trace
instead of using ext2_error().
