Subject: [PATCH] arm: prevent inlining in arxescsi.c causing build failures

The following failure is seen in routine coverage builds:

  CC [M]  drivers/scsi/arm/arxescsi.o
/tmp/cccEyiO7.s: Assembler messages:
/tmp/cccEyiO7.s:334: Error: symbol `.loop_1' is already defined

make[4]: *** [drivers/scsi/arm/arxescsi.o] Error 1

It is caused by multiple inline of arxescsi_pseudo_dma_write()
which is responsible for the above labels.  Marking the fcn
as non-inline fixes the issue.
