mpt3sas: Remove unnecessary synchronize_irq() before free_irq()
Calling synchronize_irq() right before free_irq() is quite useless. On
one hand the IRQ can easily fire again before free_irq() is entered, on
the other hand free_irq() itself calls synchronize_irq() internally (in
a race condition free way), before any state associated with the IRQ is
freed.
Patch was generated using the following semantic patch:
// <smpl>
@@
expression irq;
@@
-synchronize_irq(irq);
free_irq(irq, ...);
// </smpl>
