[pve-devel] [PATCH pve-manager] check for ext5 dir to avoid missing directory errors

[Thomas Lamprecht]

As we, for now, default to exclude ext5 from our build it's better
to make an check if its directory exists, and only then allow to
load from it. Else we can get errors on proxy startup, and when
someone passes the ext5 parameter.

Also make a indent/whitespace cleanup.
