Revert "ALSA: usx2y: Fix potential NULL pointer dereference"

Browse Source 
[ Upstream commit 4667a6fc1777ce071504bab570d3599107f4790f ]

This reverts commit a2c6433ee5.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted.  It will be fixed up "correctly" in a
later kernel change.

The original patch was incorrect, and would leak memory if the error
path the patch added was hit.
