[PATCH 01/18] virtiofs: Remove request from processing list before calling end

[Vivek Goyal]

In error path we are calling fuse_request_end() but we need to clear
FR_SENT bit as well as remove request from processing queue. Otherwise
fuse_request_end() triggers a warning as well as other issues show up.
