Remove unneeded LOCK_NONBLOCKING from vg_read() API and tools that
use it. We no longer need this flag anywhere since we now automatically
set LCK_NONBLOCK inside lock_vol() if vgs_locked().
For further details, see:
commit d52b3fd3fe
Author: Dave Wysochanski <dwysocha@redhat.com>

Remove NON_BLOCKING lock flag from tools and set a policy to auto-set.
As a simplification to the tools and further liblvm, this patch pushes
the setting of NON_BLOCKING lock flag inside the lock_vol() call.
The policy we set is if any existing VGs are currently locked, we
set the NON_BLOCKING flag.
At some point it may make sense to add this flag back if we get an
RFE from a liblvm user, but for now let's keep it as simple as
possible.
