pstore: Properly assign mem_type property

Browse Source 
commit beca3e311a49cd3c55a056096531737d7afa4361 upstream.

If mem-type is specified in the device tree
it would end up overriding the record_size
field instead of populating mem_type.

As record_size is currently parsed after the
improper assignment with default size 0 it
continued to work as expected regardless of the
value found in the device tree.

Simply changing the target field of the struct
is enough to get mem-type working as expected.
