[PATCH i-g-t] tests/core_setmaster: Change break to continue in tweak_perm function

[Bommu Krishnaiah]

Existing userspace assumes there's no gaps card’s, but I see cards
are not continues, after running “gta at core_hotunplug I am not seeing card0,
hence test is failing.

Test result before this changes:
