[PATCH] e2fsprogs: remove leftover retval check

[Lukas Czerner <lczerner@redhat.com>]

Remove leftover retval check from the read_bitmaps(). It is not
necessary as it is not previously set by any function, moreover the
retval value is not initialized in definition which may cause errors
when garbage data appears in it.

Also initialize retval to zero in definition.
