fs: do not pass __GFP_HIGHMEM to bio_alloc in do_mpage_readpage 

The mpage bio alloc cleanup accidentally removed clearing ~GFP_KERNEL
bits from the mask passed to bio_alloc.  Fix this up in a slightly
less obsfucated way that mirrors what iomap does in its readpage code.

Fixes: 77c436de01 ("mpage: pass the operation to bio_alloc")
