[PATCH] KVM: selftests: Print timer ctl register in ISTATUS assertion

From: Oliver Upton
Date: Mon Feb 12 2024 - 16:10:19 EST


Zenghui noted that the test assertion for the ISTATUS bit is printing
the current timer value instead of the control register in the case of
failure. While the assertion is sound, printing CNT isn't informative.

Change things around to actually print the CTL register value instead.
