Alexey Romanov 641608f362 zram: don't retry compress incompressible page ...

It doesn't make sense for us to retry to compress an uncompressible page
(comp_len == PAGE_SIZE) in zsmalloc slowpath, because we will be storing
it uncompressed anyway.  We can avoid wasting time on another compression
attempt.  It is enough to take lock (zcomp_stream_get) and execute the
code below.
