[Toaster] [PATCH v3 4/7] toasterui: check if setEventMask succeeded

[Ed Bartosh]

Currently toasterui ignores return value of setEventMask
command, which created confusing difference between set of
events set by this command and the real set used in the code.

Checked if setEventMask succeeded. Print error message and
exit if it's not.
