virt: tdx-guest: Remove unused and confusing function argument

The tsm_report_ops->report_new() function takes a void* argument for
implementations to use. But, TDX does not use the argument. It
relies entirely on the 'struct tsm_report'.

Despite that, the TDX code passes 'data' around needlessly from
tdx_report_new()=>tdx_report_new_locked() where it is completely
unused and ignored.

This is not just a cleanup or bike-shedding rename. The variable is a
real liability because there are 'quote_data' variables and even a
tdx_quote_buf->data[] that can get literally referred to as "data".

Remove the unused argument.
