Revert "net/smc: fix a NULL pointer dereference"

Browse Source 
[ Upstream commit 5369ead83f ]

This reverts commit e183d4e414.

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 commit causes a memory leak and does not properly fix the
issue it claims to fix.  I will send a follow-on patch to resolve this
properly.
