[PATCH] nvme-keyring: mark nvme_dhchap_psk_hash() as static inline

[Chaitanya Kulkarni <ckulkarnilinux@gmail.com>]

Fix build warning when CONFIG_NVME_KEYRING is not enabled:

  include/linux/nvme-keyring.h:57:4: warning: no previous prototype for
  function 'nvme_dhchap_psk_hash' [-Wmissing-prototypes]

The nvme_dhchap_psk_hash() stub function in the #else block is missing
the 'static inline' qualifiers that all other stub functions in the same
block have. Add them to fix the warning.
