In rvu_check_rsrc_availability() in case of invalid SSOW req, an incorrect
data is printed to error log. 'req->sso' value is printed instead of
'req->ssow'. Looks like "copy-paste" mistake.

Fix this mistake by replacing 'req->sso' with 'req->ssow'.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
