event/app: Improve error check of input parsing by spdk_strtol

Browse Source 
For the number of trace entries, change strtoull to spdk_strtoll
because no issue will occur by the change.

Besides, getopt guarantees that if an argument is followed by a
semicolon, optstring of it is not NULL. spdk_app_parse_args()
had unnecessary NULL pointer check related with this. Hence
remove those NULL pointer checks too.
