wifi: rtw88: do not ignore hardware read error during DPK

Browse Source 
[ Upstream commit 20d3c19bd8f9b498173c198eadf54580c8caa336 ]

In 'rtw8822c_dpk_cal_coef1()', do not ignore error returned
by 'check_hw_ready()' but issue a warning to denote possible
DPK issue. Compile tested only.

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