[PATCH V4 02/13] powerpc, process: Remove the unused extern dscr_default

[Anshuman Khandual]

The process context switch code no longer uses dscr_default variable
from the sysfs.c file. The variable became unused when we started
storing the CPU specific DSCR value in the PACA structure instead.
This patch just removes this extern declaration. It was originally
added by the following commit.
