[PATCH 7/8] powerpc/xmon: Drop the 'valid' variable completely in 'dump_segments'

[Anshuman Khandual <khandual@linux.vnet.ibm.com>]

Value of the 'valid' variable is zero when 'esid' is zero and it does
not matter when 'esid' is non-zero. The variable 'valid' can be dropped
from the function 'dump_segments' by checking for validity of 'esid'
inside the nested code block. This patch does that change.
