tests/shell: Fix shellcheck warnings for SC2153 in multiple scripts

Running shellcheck on some of the shell scripts, throws
below warning on shellcheck v0.6. Example:

   In tests/shell/coresight/asm_pure_loop.sh line 14:
   DATA="$DATD/perf-$TEST-$DATV.data"
          ^---^ SC2153: Possible misspelling: DATD may not be assigned, but DATA is.

Here, DATD is exported from "lib/coresight.sh" and this
warning can be ignored. Use "shellcheck disable=" to ignore
this check.
