M. Vefa Bicakci b2c04a8fab drbd: Ensure compatibility with kernel versions >= v5.2
Prior to this commit, the Ansible bootstrap procedure on StarlingX would
fail with drbd-related errors when a v5.10-based kernel was in use. The
error reported by the kernel was "invalid argument".

Upon further debugging, it was discovered that generic-netlink (genl)
messages generated by drbdsetup would be rejected by the v5.10 kernel.
After looking at the git history of the drbd-utils repository, the
following two commits were found:

$ git log -2 --pretty=ref 859151b228d3b3aacefb09d06d515a2589c22e35
859151b228d3 (netlink: Add NLA_F_NESTED flag to nested attribute, 2019-07-12)
92ade5989027 (netlink: prepare for kernel v5.2, 2019-07-12)

This issue appears to be caused by kernel versions >= 5.2 being more
strict with the validation of nested netlink attributes. The patches
required very minor context adjustments and enable the Ansible bootstrap
procedure to succeed.
