nvmf: clean up discovery args struct initialization

Replace literal zero initializers with the proper named constants:
  .result = 0  -> removed (zero is the default for unspecified fields)
  .lsp = 0     -> .lsp = NVMF_LOG_DISC_LSP_NONE

Also add the missing .timeout = NVME_DEFAULT_IOCTL_TIMEOUT in
_nvmf_discovery() to be consistent with nbft_discovery().
