[PATCH] rtw88: 8822c: Remove set but not used variable 'corr_val'

[zhengbin]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/wireless/realtek/rtw88/rtw8822c.c: In function 
rtw8822c_dpk_dc_corr_check:
drivers/net/wireless/realtek/rtw88/rtw8822c.c:2166:5: warning: variable 
corr_val set but not used [-Wunused-but-set-variable]

It is not used since commit 5227c2ee453d ("rtw88:
8822c: add SW DPK support")
