[PATCH] cxl: Fix ambiguous else warnings

[Daniel Axtens <dja@axtens.net>]

Every time I build cxl I see the following warnings:

/scratch/dja/linux-capi/drivers/misc/cxl/pci.c: In function ‘sanitise_afu_regs’:
/scratch/dja/linux-capi/drivers/misc/cxl/pci.c:712:6: warning: suggest explicit braces to avoid ambiguous ‘else’ [-Wparentheses]
   if (reg & CXL_PSL_DSISR_TRANS)
      ^
/scratch/dja/linux-capi/drivers/misc/cxl/irq.c: In function ‘fail_psl_irq’:
/scratch/dja/linux-capi/drivers/misc/cxl/irq.c:184:5: warning: suggest explicit braces to avoid ambiguous ‘else’ [-Wparentheses]
  if (irq_info->dsisr & CXL_PSL_DSISR_TRANS)
     ^

They're annoying. Fix them by inserting the braces.
