zram: remove zcomp_stream_put() from write_incompressible_page() 

We cannot and should not put per-CPU compression stream in
write_incompressible_page() because that function never gets any
per-CPU streams in the first place.  It's zram_write_page() that
puts the stream before it calls write_incompressible_page().
