tools/mgmt-tester: Add param check callback for LE Set Adv Params

The interval_min and interval_max in LE Set Advertising Parameters
command are changed/updated often whenever the values are tuned in the
kernel, and it causes some tests failure.

This patch adds a parameter check callback for LE Set Advertising
Parameters command to ignore the interval_min and interval_max
parameters.
