Eiichi Tsukata c7cd82b905 vsock: prevent unnecessary refcnt inc for nonblocking connect ...

Currently vosck_connect() increments sock refcount for nonblocking
socket each time it's called, which can lead to memory leak if
it's called multiple times because connect timeout function decrements
sock refcount only once.

Fixes it by making vsock_connect() return -EALREADY immediately when
sock state is already SS_CONNECTING.
