[PATCH] dtc: remove some warnings

[Stephen Rothwell]

I assume that these variables were used in the past but not removed when
their usage was removed.

Fixes these warnings:

scripts/dtc/dtc.c: In function 'main':
scripts/dtc/dtc.c:102:17: warning: variable 'check' set but not used [-Wunused-but-set-variable]
scripts/dtc/flattree.c: In function 'flat_read_mem_reserve':
scripts/dtc/flattree.c:700:14: warning: variable 'p' set but not used [-Wunused-but-set-variable]
