mlxsw: spectrum: Do not assume PAUSE frames are disabled

When ieee_setpfc() gets called, PAUSE frames are not necessarily
disabled on the port.

Check if PAUSE frames are disabled or enabled and configure the port's
headroom buffer accordingly.

Fixes: d81a6bdb87ce ("mlxsw: spectrum: Add IEEE 802.1Qbb PFC support")
