[PATCH v1 1/6] shared-memory: drop check for mmap file being located on tmpfs

[Christian Ebner <c.ebner@proxmox.com>]

For some usecases, e.g. s3 client request counters, the mmapped file
should outlive a reboot and must therefore be placed on persistent
storage, not just a tmpfs. Drop the explicit check for the file being
located on tmpfs.
