smb_getsock: always wait for write socket too

Browse Source 
... the protocol is doing read/write a lot, so it needs to write often
even when downloading. A more proper fix could check for eactly when it
wants to write and only ask for it then.

Without this fix, an SMB download could easily get stuck when the event-driven
API was used.

Closes #2768
