staging: rtl8723bs: Refactor setCCKFilterCoefficient to remove duplicated rtw_write8() calls

Previously, the function used 16 individual and repetitive rtw_write8()
calls (8 for each channel condition) to set the filter coefficients.

The new implementation uses a table pointer to select the appropriate
swingtable and iterates through the 8-byte coefficient array using a
single for loop. This achieves the same result without changing logic.
