Corrected JPEG encoding's libva log trace.

Issue: The format of JPEG encoding's log
dumped by libva trace was messy:

[51461.446753] 	element[0] =
[51461.446837] 	--VAQMatrixBufferJPEG
[51461.446850] 	load_lum_quantiser_matrix = 1[51461.446858]
	[51461.446864] 	0x03[51461.446873] 	0x02[51461.446880] 	0x02[51461.446887] 	0x03[51461.446895] 	0x02[51461.446902] 	0x02[51461.446909] 	0x03[51461.446916] 	0x03[51461.446923]
	[51461.446930] 	0x03[51461.446937]

Solution: Corrected that log trace.
