Rex Zhang e23d6ba502 dmaengine: idxd: Move dma_free_coherent() out of spinlocked context 
[ Upstream commit e271c0ba3f919c48e90c64b703538fbb7865cb63 ]

Task may be rescheduled within dma_free_coherent(). So dma_free_coherent()
can't be called between spin_lock() and spin_unlock() to avoid Call Trace:
    Call Trace:
    <TASK>
    dump_stack_lvl+0x37/0x50
    __might_resched+0x16a/0x1c0
    vunmap+0x2c/0x70

    do_syscall_64+0x44/0xa0
    entry_SYSCALL_64_after_hwframe+0x6e/0xd8
Move it out of the context.
