[PATCH blktests v2 1/1] nvme/{041,042,043,044,045}: check dhchap_ctrl_secret support by nvme-fabrics

[Shin'ichiro Kawasaki]

The kernel commit d68006348288 ("nvme: rework NVME_AUTH Kconfig
selection") in v6.7-rc1 introduced a new kernel config option
NVME_HOST_AUTH. When the option is disabled, nvme test cases from 041 to
045 fail because nvme-fabrics module does not support the feature
dhchap_ctrl_secret.

To check the requirement, add _require_kernel_nvme_fabrics_feature()
which refers /dev/nvme-fabrics and checks if the specified feature
string is found or not. Call it to check dhchap_ctrl_secret support in
require() of the test cases.

This change relies on the kernel commit 1697d7d4c5ef ("nvme: blank out
authentication fabrics options if not configured").
