Subject: [PATCH v5 1/3] man/man2const/PR_FUTEX_HASH.2const: Update as of Linux v6.17-rc2

The PR_FUTEX_HASH prctl interface was updated shortly before the release
of v6.16. The changes are:
- the functionality was disabled in v6.16 and enabled v6.17-rc1 after
  some updates the address performance concerns.
- the "IMMUTABLE" functionality was removed.

Update the page accordingly.
