thunderbolt: Fix sideband register access in usb4_port_sw_margin_errors()
The READ_SW_MARGIN_ERR (RDSW) completion payload is returned in the USB4
sideband data window, but the location differs between standard and
extended error counters.
Standard error counters are returned in USB4_SB_METADATA and fit within
a single dword. Extended error counters require 4 dwords and are returned
in USB4_SB_DATA.
Add conditional logic to select the appropriate register based on the
dwords parameter that corresponds with error counter type.
