test: reduce time for function reentrancy test
test: reduce time for function reentrancy test

Reduced test duration for func_reentrancy_autotest.
Reduced MAX_LPM_ITER_TIMES, introduced new macro
MAX_ITER_ONCE to reduce the unique key check and
altered the macro MAX_ITER_TIMES to MAX_ITER_MULTI.
Combined for loops thereby reduced snprintf calls
and repeated iterations.
Such that the duration is less than 10 seconds.
