[PATCH] of: reserved-memory: Print allocation/reservation failures as error

[Vincent Whitchurch]

If the allocation/reservation of reserved-memory fails, it is normally
an error, so print it as an error so that it doesn't get hidden from the
console due to the loglevel.  Also make the allocation failure include
the size just like the reservation failure.
