Subject: [PATCH 5.15/6.1/6.6] nvmet-fc: Remove unused functions

[ Upstream commit 1b304c006b0fb4f0517a8c4ba8c46e88f48a069c ]

The functions nvmet_fc_iodnum() and nvmet_fc_fodnum() are currently
unutilized.

Following commit c53432030d86 ("nvme-fabrics: Add target support for FC
transport"), which introduced these two functions, they have not been
used at all in practice.

Remove them to resolve the compiler warnings.

Fix follow errors with clang-19 when W=1e:
  drivers/nvme/target/fc.c:177:1: error: unused function 'nvmet_fc_iodnum' [-Werror,-Wunused-function]
    177 | nvmet_fc_iodnum(struct nvmet_fc_ls_iod *iodptr)
        | ^~~~~~~~~~~~~~~
  drivers/nvme/target/fc.c:183:1: error: unused function 'nvmet_fc_fodnum' [-Werror,-Wunused-function]
    183 | nvmet_fc_fodnum(struct nvmet_fc_fcp_iod *fodptr)
        | ^~~~~~~~~~~~~~~
