Fix page allocation flags in grow_dev_page()

grow_dev_page() simply passes GFP_NOFS to find_or_create_page.  This means
the allocation of radix tree nodes is done with GFP_NOFS and the allocation
of a new page is done using GFP_NOFS.

The mapping has a flags field that contains the necessary allocation flags
for the page cache allocation.  These need to be consulted in order to get
DMA and HIGHMEM allocations etc right.  And yes a blockdev could be
allowing Highmem allocations if its a ramdisk.
