SSL: removed redundant "pkey" variable.

It was accidentally introduced in 77436d9951a1 (1.15.9).  In MSVC 2015
and more recent MSVC versions it triggers warning C4456 (declaration of
'pkey' hides previous local declaration).  Previously, all such warnings
were resolved in 2a621245f4cf.

Reported by Steve Stevenson.
