Fix partition search for ramdisk-recovery image

Since ramdisk-recovery.img is mounted on memory space and it also has
the same label with physical partition, the target partition could be
wrong if the ram-mounted partition is searched first. To resolve it,
this fixes partition search as excepting the devices including 'ram'
on its node name.
