wifi: rtlwifi: 8192de: correct checking of IQK reload

Browse source 
Since IQK could spend time, we make a cache of IQK result matrix that looks
like iqk_matrix[channel_idx].val[x][y], and we can reload the matrix if we
have made a cache. To determine a cache is made, we check
iqk_matrix[channel_idx].val[0][0].

The initial commit 7274a8c229 ("rtlwifi: rtl8192de: Merge phy routines")
make a mistake that checks incorrect iqk_matrix[channel_idx].val[0] that
is always true, and this mistake is found by commit ee3db469dd
("wifi: rtlwifi: remove always-true condition pointed out by GCC 12"), so
I recall the vendor driver to find fix and apply the correctness.
