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.
