[Devel] [VZ10 v2 12/21] ve/kernfs: Fix when !CONFIG_VE

[Vladimir Riabchun]

1. Have kernfs_super_info->ve unconditionally
2. Add missing static inline for stub functions
3. Fix kernfs_ve_allowed arguments so they match
4. Replace removed has_ns with kernfs_ns_enabled in kernfs_find_ns

https://virtuozzo.atlassian.net/browse/VSTOR-130116

Feature: !CONFIG_VE build
