Thomas Schoebel-Theuer e7464b3c02 all: correct error code EIO 
The error code -EIO should always refer to a problem of
lower storage laysers. Thus MARS should not generate that
code itself, but other ones.

Thomas Schoebel-Theuer 21991f3cf3 logger: fix scarce race on replay EOF 
This led to annoying error messages like checksumming mismatches
or record sequence number mismatches etc.
AFAIK the data integrity was not in danger (since the checks
masked out any potentially harmful actions).
