HDD labels that include spaces aren't recognised by the UI

[prl]

Reproduction steps

Change the label on a USB drive (e.g thumb drive) to have a label that includes spaces. Connect the drive to the T3.

In MENU>Sources, the drive will appear with its location name (e.g. Front USB Slot) rather than its label. Similarly in MEDIA, YELLOW Location.
