tools/blktap2: fix build errors caused by Werror, remove blkif_op_name

-O2 -Wall -Werror triggers these warnings:

../include/blktaplib.h:235: warning: 'blkif_op_name' defined but not used

blkif_op_name[] is odd and appearently not used according to google, except in
an 7 years old blkdump.c which would not compile anyway with current blktap.
