Gao Xiang 15cc248e7e erofs: avoid allocating DEFLATE streams before mounting 
commit 80eb4f62056d6ae709bdd0636ab96ce660f494b2 upstream.

Currently, each DEFLATE stream takes one 32 KiB permanent internal
window buffer even if there is no running instance which uses DEFLATE
algorithm.

It's unexpected and wasteful on embedded devices with limited resources
and servers with hundreds of CPU cores if DEFLATE is enabled but unused.

Fixes: ffa09b3bd024 ("erofs: DEFLATE compression support")
