Subject: ext3: return after ext3_error in case of failures
From: "Aneesh Kumar K.V" <[EMAIL PROTECTED]>
This fixes some instances where we were continuing after calling
ext3_error. ext3_error calls panic only if errors=panic mount option is
set. So we need to make sure we return correctly after ext3_error call
