fabrics: Lower log level in __nvmf_add_ctrl

9df8676 ("Add logging functionality to libnvme") introduced the
logging. The log level for writing to /dev/nvme-fabrics was set on
NOTICE because the kernel reports also status information such
EALREADY which is a soft error.

866c288 ("fabrics: update log level for write failures")
increased the log level without taking this into account.

Drop back to NOTICE level to avoid error message when doing

  $ nvme connect-all ....
  Failed to write to /dev/nvme-fabrics: Operation already in progress
