It looks like it could be a config problem.. The crash happens around
these two symbol "af9005_rc_keys", and "af9005_rc_keys_size" , and they
are both defined inside af9005-remote.c different from where the init
functions is lcoated .. af9005-remote.c needs a special config
CONFIG_DVB_USB_AF9005_REMOTE to get compiled which you have disabled.. 

I think there's no compile warning cause symbol_get() creates weak
symbols when CONFIG_MODULES is off..
