bugzilla: 46903

--------------------------------

[ Upstream commit 4ba9e516 ]

hw_event_sas_phy_up() is used in hardirq/softirq context:

 pm8001_interrupt_handler_msix() || pm8001_interrupt_handler_intx() || pm8001_tasklet
   => PM8001_CHIP_DISP->isr() = pm80xx_chip_isr()
     => process_oq() [spin_lock_irqsave(&pm8001_ha->lock,)]
       => process_one_iomb()
         => mpi_hw_event()
           => hw_event_sas_phy_up()
             => msleep(200)

Revert the msleep() back to an mdelay() to avoid sleeping in atomic
context.
