[PATCH 5.15 28/39] scsi: qla2xxx: Use named initializers for port_[d]state_str

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Gleb Chesnokov <Chesnokov.G@raidix.com>

[ Upstream commit 6e0e85d39e528da2915a2da261195f81bfde6915 ]

Make port_state_str and port_dstate_str a little more readable and
maintainable by using named initializers.

Also convert FCS_* macros into an enum.
