MLK-20240-2 sata: ahsata: Fix wrong operand for checking SERR DIAG_X
Fix coverity issue CID 3261683: Wrong operator used (CONSTANT_EXPRESSION_RESULT)
operator_confusion: ({...; __v;}) | 67108864 is always 1/true regardless of the values
of its operand. This occurs as the logical operand of !
When DIAG_X is set, the PHY COMINIT signal is detected, so should use '&' to check
whether it is set.
