IB/hfi1: Mask out A bit from psn trace

[ Upstream commit d0a2f454713a42447ee4007582c0e43c47bcf230 ]

The trace logic prior to the fixes below used to mask the
A bit from the psn. It now mistakenly displays the A bit,
which is already displayed separately.

Fix by adding the appropriate mask to the psn tracing.

Fixes: 228d2af1b723 ("IB/hfi1: Separate input/output header tracing")
Fixes: 863cf89d472f ("IB/hfi1: Add 16B trace support")
