extras: Turn eager-lock off for gluster-block

Browse Source 
With the current implementation of eager-lock FINODELK is taking so much
time that cassandra workload times out and errors out. AFR eager-locking
needs to be changed similar to EC eager-locking to make things work
as expected. In the interim, it is better to turn it off

This is how the profile looks if eager-lock is turned on:
      0.35     628.26 us      64.00 us  129882.00 us          42278    FXATTROP

This is how profile looks if eager-lock is turned off:
