[2/3] kernel-shark-qt: Change the input argument of kshark_dump_entry() to const.

Commit Message

Yordan Karadzhov Aug. 3, 2018, 1:07 p.m. UTC

kshark_dump_entry() should not be able to modify the content of its input
argument (kshark_entry) which is being dumped to a string. The type of the
argument is changed from "struct kshark_entry*" to "const struct kshark_entry*"
