Subject: [PATCH net 2/3] sh_eth: fix TRSCER mask for R7S72100

According  to  the RZ/A1H Group, RZ/A1M Group User's Manual: Hardware,
Rev. 4.00, the TRSCER register has bit 9 reserved, hence we can't use
the driver's default TRSCER mask.  Add the explicit initializer for
sh_eth_cpu_data::trscer_err_mask for R7S72100.

Fixes: db893473d313 ("sh_eth: Add support for r7s72100")
