Deadlock during SQLDriverConnect()

[aleksei-i]

We call SQLDriverConnect() which get lock using ENTER_HDBC(). Then the SQLSetConnectOptionW() is called which also get lock using ENTER_HDBC(). The second ENTER_HDBC() cause the deadlock.

The test:
CheckBeforeConnect(SQL_ATTR_LOGIN_TIMEOUT, value, value); This function set the connect attribute before connection using SQLSetConnectAttr() and then calls SQLDriverConnect().
