ddeinitialize fix

[Rein Klazes]

hi,

This solves the "err:ddeml:Release_reserved_mutex ReleaseMutex failed"
error that causes a crash in pegasus mail, and makes some other
programs refuse to run when another application has called
DdeInitialize() before.

Changelog:
	dlls/user	: ddeml.c
	Handle the case in if the DdeInstanceMutex is already created
in 
	another process.
