mesa: fix error handling for some glGet* functions

According to the man page, it should trigger a GL_INVALID_OPERATION
while calling some glGet* functions inside glBegin and glEnd.

This patch dose handle the following functions:
 glGetBooleanv
 glGetFloatv
 glGetIntegerv
 glGetInteger64v
 glGetDoublev
