[PATCH] makedumpfile, sadump: fix warning about unused variable

[HATAYAMA Daisuke]

Recent gcc does unused variable checking at default of -Wall and
outputs the following warning:

./sadump_info.c: In function 'sadump_initialize_bitmap_memory':
./sadump_info.c:754: warning: variable 'dumpable_bitmap_len' set but not used

Delete it as suggested.
