bdev/compress: increase mbuf pool size

Browse Source 
Was 1024 but w/the performance optimizations we can now use up
to 4 mbufs per outstanding IO so going to 8192 only uses 1MB of
mem and gives us better head room before we have to start queueing
compression operations to wait for mbufs. Note: the mbuf pool is
shared accross all virtual compression bdevs.
