ext4: Fix mballoc BUG when running compilebench
From: Aneesh Kumar K.V <aneesh.kumar@xxxxxxxxxxxxxxxxxx>
This fix the mballoc bug when running compile bench.
Instead of using direct division even though the arguments
are 32 bits we retain do_div. This would be needed if we
move to 64 bit logical block number.

ext4: Return after ext4_error in case of failures
From: Aneesh Kumar K.V <aneesh.kumar@xxxxxxxxxxxxxxxxxx>
This fix some instances where we were continuing
after calling ext4_error. ext4_error call panic
only if errors=panic mount option is set. So
we need to make sure we return correctly after
ext4_error call
