erofs: kill use_vmap module parameter
As Christoph said [1],
"vm_map_ram is supposed to generally behave better. So if
it doesn't please report that that to the arch maintainer
and linux-mm so that they can look into the issue. Having
user make choices of deep down kernel internals is just
a horrible interface.
Please talk to maintainers of other bits of the kernel
if you see issues and / or need enhancements. "
Let's redo the previous conclusion and kill the vmap
approach.
