[PATCH 1/4] spi: s3c64xx: rename goto labels to meaningful names

[Andi Shyti <andi.shyti@xxxxxxxxxxx>]

In goto labels of the style of

  err4:
  err3:
  err2:
  err1:

is complex to insert in between new errors without renaming all
the goto statments. Replace the errX naming style to meaningful
names in order to make it easier to insert new goto exit ponts.
