Subject: sg3_utils: Strip out trailing info from vendor info products fields in inquiry
commit 1756f3b04d4c45d7a0d78e128786b2a1c619565e
Date:   Tue Apr 15 10:31:23 2014 -0500
Reference: bnc#863357


sginfo <device> prints out various fields such as Vendor and Product in
INQUIRY response with spaces (0x20) characters.
This can confuse scripts some users have.
Strip out those trailing spaces (if any).
