[PATCH v10 06/12] ima: Use designated initializers for struct ima_event_data

[Thiago Jung Bauermann <bauerman@linux.ibm.com>]

Designated initializers allow specifying only the members of the struct
that need initialization. Non-mentioned members are initialized to zero.

This makes the code a bit clearer (particularly in ima_add_boot_aggregate()
and also allows adding a new member to the struct without having to update
all struct initializations.
