Lock in connection pool held for too long [DNET970]

[firebird-automations]

Submitted by: @cincuranet

The lock in `GetConnection` is held even as the `FbConnectionInternal.Connect` is performed. It can be released sooner and the remaining "plumbing" work can be done outside the lock. This observation comes from cincuranet/FirebirdSql.Data.FirebirdClient#105.
