Subject: [PATCH v2 1/5] x86/virt/tdx: Rename _offset to _member for TD_SYSINFO_MAP() macro

TD_SYSINFO_MAP() macro actually takes the member of the 'struct
tdx_tdmr_sysinfo' as the second argument and uses the offsetof() to
calculate the offset for that member.

Rename the macro argument _offset to _member to reflect this.
