ipvs: change some data types from int to bool
Change the data type of the following variables from int to bool
across ipvs code:
- found
- loop
- need_full_dest
- need_full_svc
- payload_csum
Also change the following functions to use bool full_entry param
instead of int:
- ip_vs_genl_parse_dest()
- ip_vs_genl_parse_service()
This patch does not change any functionality but makes the source
code slightly easier to read.
