[USER32] Zero out buffer in SYSPARAMS_Load

[Felix Nawothnig]

All my menu went flat because my UserPreferences key is 00000000 (too 
few zeros) which resulted SystemParametersInfo reading the setting from 
uninitialized memory...

ChangeLog:
Clear buffer before querying the registry in SYSPARAMS_Load.
