[PATCH] dedupe_percentage should work even if compress_percentage is not set

[PATCH] dedupe_percentage should work even if compress_percentage is not set 

Currently dedupe_percentage option does not work properly if compress_percentage
is not set. This can be easily demonstrated using the following job file:

[job-/dev/dm-0]
filename=/dev/dm-0
rw=randwrite
blocksize=4096
direct=1
ioengine=libaio
iodepth=32
dedupe_percentage=50
time_based=1
runtime=5
numjobs=1

All writes will contain zeroes for the above job file.

The problem is in fill_io_buffer() function that switches dedupe random state
only if o->compress_percentage is set.                                                                                                                                                                         

This patch updates the condition appropriately in fill_io_buffer()
appropriately.

Thanks, looks good, applied.
