[media] of: reserved_mem: restore old behavior when no region is defined

Browse Source 
Change return value back to -ENODEV when no region is defined for given
device. This restores old behavior of this function, as some drivers rely
on such error code.

Fixes: 59ce4039727ef40 ("of: reserved_mem: add support for using more than
       one region for given device")
