    disk/nata: Fix panic caused by 'callouts: malloc limit exceeded'
    
    Call callout_terminate() in ata_free_request() to fix the leak.
    
    There was a callout leak before and could easily cause the following
    panic:
    
    	panic: callouts: malloc limit exceeded
    	cpuid = 1
    	Trace beginning at frame 0xfffff8005cd9d2a8
    	_kmalloc() at _kmalloc+0xb09 0xffffffff80658519
    	_kmalloc() at _kmalloc+0xb09 0xffffffff80658519
    	callout_reset() at callout_reset+0x13f 0xffffffff80687adf
    	ata_begin_transaction() at ata_begin_transaction+0x1a7 0xffffffff8032bf47
    	ata_start() at ata_start+0x190 0xffffffff80330140
    	ata_queue_request() at ata_queue_request+0x100 0xffffffff80330390
    	Debugger("panic")
