user - EditWndProc_common - Ignore WM_USER messages which are not sent from a vdm

[Stefan Siebert]

Hello,

this patch fixes a Notes Client crash when building the server console
tab (administration client). After creating a text control for console 
commands it sends uncaught WM_USER messages which get interpreted by 
Wine as 16Bit messages and crashes badly due to NULL pointers.

Changelog: user/edit.c - EditWndProc_common - Ignore WM_USER messages 
which are not sent from a vdm
