Initialize PIN logged_in field for cards that do not support PIN info 

Commit 2f10de4f5c ("use sc_pkcs15_get_pin_info in C_GetTokenInfo")
introduced dependency of logged in state returned for session
by C_GetTokenInfo() on logged_in field of that session slot PIN.

This field is updated by sending pin_cmd of type SC_PIN_CMD_GET_INFO to
card.
However, not all cards support such pin_cmd type (in fact, majority of
them don't). In this case logged_in field is usually left zero-initialized
which means SC_PIN_STATE_LOGGED_OUT.

With such logged_in field value C_GetTokenInfo() always returns
CKS_R{O,W}_PUBLIC_SESSION, instead of CKS_R{O,W}_USER_FUNCTIONS when
logged in.

At least Firefox (and probably other NSS-based software, too) is confused
by such value and keeps repeating PIN prompts a few times until it
ultimately considers that logging in to this slot has failed.

Fix this by initializing PIN logged_in field to SC_PIN_STATE_UNKNOWN for
cards that do not support SC_PIN_CMD_GET_INFO pin_cmd.
