Roger Pau Monné f4576dd975 x86/dma_bounce: revert r289834 and r289836 
The new load_ma implementation can cause dereferences when used with
certain drivers, back it out until the reason is found:

Fatal trap 12: page fault while in kernel mode
cpuid = 11; apic id = 03
fault virtual address   = 0x30
fault code              = supervisor read data, page not present
instruction pointer     = 0x20:0xffffffff808a2d22
stack pointer           = 0x28:0xfffffe07cc737710
frame pointer           = 0x28:0xfffffe07cc737790
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 13 (g_down)
trap number             = 12
