Subject: [PATCH] dmaengine: mmp_pdma: fix mismerge

The merge between 2b7f65b11d87f "mmp_pdma: Style neatening" and
8010dad55a0ab0 "dma: add dma_get_any_slave_channel(), for use in of_xlate()"
caused a build error by leaving obsolete code in place:

  mmp_pdma.c: In function 'mmp_pdma_dma_xlate':
  mmp_pdma.c:909:31: error: 'candidate' undeclared
  mmp_pdma.c:912:3: error: label 'retry' used but not defined
  mmp_pdma.c:901:24: warning: unused variable 'c' [-Wunused-variable]

This removes the extraneous lines.
