[27/43] drivers/net/sfc: fix sparse warnings: Should it be static?

Impact: Include header file and include the function under the same
condition as in the header file.  If CONFIG_SFS_MTD is not defined
than the functions 'efx_mtd_remove' and 'efx_mtd_rename' are defined
'static inline' with an empty function body in the header file.

Fix this sparse warnings:
  drivers/net/sfc/mtd.c:204:6: warning: symbol 'efx_mtd_remove' was not declared. Should it be static?
  drivers/net/sfc/mtd.c:221:6: warning: symbol 'efx_mtd_rename' was not declared. Should it be static?
  drivers/net/sfc/mtd.c:230:5: warning: symbol 'efx_mtd_probe' was not declared. Should it be static?

This is wrong.  The entire file is conditional on CONFIG_SFC_MTD.

Ben.

Even better than. It's actually not wrong, just done twice, so we can
omit it, thank you Ben. I'll send an update.
