More tracing in egl_dri2.c

I see. When the second display is initialized, there is still an active
context, it seems (dri2_display_release should not be called on the first call
to dri2_make_current):

libEGL debug: Native platform type: drm (autodetected)
libEGL debug: dri2_initialize 0x90d7a0 0x9a2f10 (dri2_dpy=(null))
libEGL debug: the best driver is DRI2
libEGL debug: EGL user error 0x3009 (EGL_BAD_MATCH) in dri2_create_context
libEGL debug: dri2_make_current 0x90d7a0 0x9a2f10 (nil) (nil) 0x99dbf0
libEGL debug: dri2_display_release 0x9a2f10 2
refcount -> 1

This causes the reference count to drop to zero later on:
libEGL debug: dri2_make_current 0x90d7a0 0x9a2f10 (nil) (nil) (nil)
libEGL debug: dri2_display_release 0x9a2f10 1
refcount -> 0 => display is destroyed
libEGL debug: dri2_make_current 0x90d7a0 0x9a2f10 (nil) (nil) 0x99dbf0
libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglMakeCurrent

One more patch to confirm this.
