[PATCH 3/4] text-based mount: Set addr= option in nfs_try_mount_foo()

[Chuck Lever <chuck.lever@oracle.com>]

When retrying a mount request with a different server address, the
addr= option may change each time through the fg/bg loop.

Instead of setting the addr= option in nfs_validate_options(), set it
in nfs_try_mount_v2v3() and nfs_try_mount_v4().  This is much the
same thing we did recently with the version-specific mount options
which might change each time through the fg/bg retry loop.
