iobufs: make iobref container size dynamic
With gfapi we can receive read/write size beyond the natural limits
of FUSE and NFS server. iobref was hardcoded to hold iobuf refs up
to 16 in count, which imposes a natural limit of 2MB with 128KB page
sizes of read-ahead and io-cache. Fix this by making iobref's iobuf
ref container size dynamic.
