ext2: fix sleeping in atomic bugs on error
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().
