Prevent escaping of internal names with leading numbers to fix graph processing

Browse source 
With serials like

Node             SN                   Model                                    Namespace Usage                      Format           FW Rev

the internal names (by serial number) were rewritten to

Field 	Internal name 	Type 	Warn 	Crit 	Info
/dev/nvme0n1 	_85S100HTYST_w 	derive 	  	  	 
/dev/nvme1n1 	S4GENX0N713949_w 	derive

--> the trailing underscore in case of nvme0n1 created problems in graph processing:

[RRD ERROR] Unable to graph /var/cache/munin/www/lxdserver/....agitos.de/nvme_bytes-month.png : undefined vname c285S100HTYST_r

Therefore I added a prefix 'SN_' for internal names.
