zonefs changes for 5.10

This pull request introduces the following changes to zonefs:

* Add the "explicit-open" mount option to automatically issue a
  REQ_OP_ZONE_OPEN command to the device whenever a sequential zone file
  is open for writing for the first time. This avoids "insufficient zone
  resources" errors for write operations on some drives with limited
  zone resources or on ZNS drives with a limited number of active zones.
  From Johannes.
