The latest Linux NVMe host (e.g. Linux kernel 5.12) have improved
the quality of multipath but still has an issue such that ANA state
is observed to be invalid even after connection is successfully
created.
By code inspection and system test, initializing ANA state may be
delayed even after connection is successfully created.
We can insert a short sleep but it will be better to retry checking
with timeout. The created function check_ana_state() is applied to
the remaining cases.
This fixes the part of the issue #1819.
