Subject: [PATCH] [media] pvrusb2: remove redundant check on cnt > 8

From: Colin Ian King <colin.king@...onical.com>

The 2nd check of cnt > 8 is redundant as cnt is already checked
and thresholded to a maximum of 8 a few statements earlier.
Remove this redundant 2nd check.

Detected by CoverityScan, CID#114281 ("Logically dead code")
