[mellanox]: Update SDK to 4.4.2308, FW to *.2008.2308 (#6552)

Bugs fixes:
    All | Kernel | During system reload when CPU is loaded with heavy traffic, a Kernel Panic may occur.
    All | Modules, Port split | FW stuck when device rebooted with locked Optical Transceivers in split mode
    Spectrum-3 | PFC | On Spectrum-3 systems, slow reaction time to Rx pause packets on 40GbE ports may lead to buffer overflow on servers.
    Spectrum-3 | SN4700, Port Split | On rare occasion SN4700, conducting 100G split (4x25G) in NRZ when splitter port 1 or 2 are down, ports 3 and 4 will also go down.

Enahncments:
    All | Kernel | new notification on ISSU start, so other kernel drivers can disable any interface to ASIC
