condlog doesn't actually handle verbosity levels gerater than 4
correctly when logging to syslog (there is no loglevel 8). I didn't
even realize that there were any condlog(5, ...) calls.

This is a resend of my previous patch 2/2, incorporating both of
Martin's suggestions.

libmultipath: fix false removes in dmevents polling code

dm_is_mpath() would return 0 if either a device was not a multipath
device or if the libdevmapper command failed. Because dm_is_mpath()
didn't distinguish between these situations, dm_get_events() could
assume that a device was not really a multipath device, when in fact it
was, and the libdevmappe

struct bioctx includes the ref refcount_t to track the number of I/O
fragments used to process a target BIO as well as ensure that the zone
of the BIO is kept in the active state throughout the lifetime of the
BIO. However, since decrementing of this reference count is done in the
target .end_io me
