[PATCH net-next v3 6/9] eth: fbnic: set the netmem TX frag size limit to 32KB

The TX descriptor length field (FBNIC_TWD_LEN_MASK) is 16 bits wide.
Set the netmem TX frag size limit to the largest power of 2 which fits,
like bnxt. With 64K pages this also lowers the PAGE_SIZE default, whose
64KB frags don't fit the length field.
