For libfc to register FDMI attributes we need to do two things:
- Set the appropriate fc_host attributes that libfc will use to form the
FDMI registration commands
- Set lport->fdmi_enabled to 1

The newly added suspend/resume support causes harmless warnings when
CONFIG_PM is disabled:
smartpqi/smartpqi_init.c:5147:12: error: 'pqi_ctrl_wait_for_pending_io' defined but not used [-Werror=unused-function]
smartpqi/smartpqi_init.c:2019:13: error: 'pqi_wait_until_lun_reset_finished' defined but not used [-Werror=unused-function]
smartpqi/smartpqi_init.c:2013:13: error: 'pqi_wait_until_scan_finished' defined but not used [-Werror=unused-function]
We can avoid the warnings by removing the #ifdef around the handlers and
instead marking them as __maybe_unused, which will let gcc drop the
unused code silently.

When copying attributes, the len argument was padded out and the
resulting memcpy() would copy beyond the end of the source buffer.
Avoid this, and use size_t for val_len to avoid all the casts.
Similarly, avoid source buffer casts and use void *.
Additionally enforces val_len can be represented by u16 and that the DMA
buffer was not overflowed. Fixes the size of mfa, which is not
FC_FDMI_PORT_ATTR_MAXFRAMESIZE_LEN (but it will be padded up to 4). This
was noticed by the future CONFIG_FORTIFY_SOURCE checks.
