2: Unsupported version

[mariusmotea]

Hi,

Recently i was unable to compile and run this successfully on arm64 platform because of the error from the subject. Seams version2 is no longer build in nfs-utils.

The fix is to remove the mention of version 2 protocol here:
local flags=('--nfs-version' "$requested_version" '--no-nfs-version' 2)
and keep just:
local flags=('--nfs-version' "$requested_version")

I can confirm the issue and the fix.
