Jonathan Brassow f0be9ac904 cmirrord: Prevent secondary checkpoints from corrupting bitmaps 
The bug addressed by this patch manifested itself during testing
by showing a mirror that never became 'in-sync' after creation.
The bug is isolated to distributions that do not have support
for openAIS checkpointing (i.e. > RHEL6, > F16).

When a node joins a group that is managing a mirror log, the other
machines in the group send it a checkpoint representing the current
state of the bitmap.  More than one machine can send a checkpoint,
but only the initial one should be imported.  Once the bitmap state
has been imported from the initial checkpoint, operations (such
as resync, mark, and clear operations) can begin.  When subsequent
checkpoints are allowed to be imported, it has the effect of erasing
all the log operations between the initial checkpoint and the ones
that follow.

When cmirrord was updated to handle the absence of openAIS
checkpointing (commit 62e38da133),
the new import_checkpoint() function failed to honor the 'no_read'
parameter.  This parameter was designed to avoid reading all but
the initial checkpoint.  Honoring this parameter has solved the
issue of corrupting bitmap data with secondary checkpoints.
