[PATCH] ntdll: Do not override existing context's EAX when dispatching user APC.

[Gabriel Ivăncescu]

Fixes a regression introduced by 175a3649ba04daaad3f2b5b62d6bfe091d6a9e46,
which caused Winamp's in_wave module to crash when playing a wav file
(the previous behavior only changed EAX when there was no context).
