Conrad Meyer dab6195cd3 FUSE: Bump maximum IO size to enable more performant operation 
Various components restrict size of IO passed up to the userspace filesystem
based on the mount's f_iosize value.  The previous default of PAGE_SIZE
is anemic, even for normal filesystems, but especially considering every
FUSE operation involves a kernel <-> userspace IPC upcall.

Bump to DFLTPHYS (currently 64kB) to match other FUSE implementations.

Anecdotally, Jakub reports IO read performance increased from 600 MB/s ->
2700 MB/s with a basic RAM-backed FUSE filesystem.
