[ Upstream commit 85099c7ce4f9e64c66aa397cd9a37473637ab891 ]

In rtw89_sta_info_get_iter() 'status->he_gi' is compared to array size.
But then 'rate->he_gi' is used as array index instead of 'status->he_gi'.
This can lead to go beyond array boundaries in case of 'rate->he_gi' is
not equal to 'status->he_gi' and is bigger than array size. Looks like
"copy-paste" mistake.

Fix this mistake by replacing 'rate->he_gi' with 'status->he_gi'.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
