Fix ASAN failure in bitrev_test
Previously while testing osmo_nibble_shift_left_unal() following error was triggered by AddressSanitizer upon offs == 12 and the last sh_chk line, i.e. shift left of 12 nibbles from in2: ==3890== ERROR: AddressSanitizer: stack-buffer-overflow on address 0xbff5b5b6 at pc 0xb6186862 bp 0xbff5b4a8 sp 0xbff5b49c READ of size 1 at 0xbff5b5b6 thread T0 #0 0xb6186861 (/home/msuraev/source/gsm/libosmocore/src/.libs/libosmocore.so.7.0.0+0xc861) #1 0x8049d8b (/home/msuraev/source/gsm/libosmocore/tests/bits/.libs/lt-bitrev_test+0x8049d8b) #2 0x804a9d1 (/home/msuraev/source/gsm/libosmocore/tests/bits/.libs/lt-bitrev_test+0x804a9d1) #3 0xb5fe3af2 (/lib/i386-linux-gnu/libc-2.19.so+0x19af2) #4 0x8048a30 (/home/msuraev/source/gsm/libosmocore/tests/bits/.libs/lt-bitrev_test+0x8048a30) Address 0xbff5b5b6 is located at offset 38 in frame <main> of T0's stack: This frame has 3 object(s): [32, 38) 'in2' [96, 104) 'out' [160, 168) 'in1' The reason is incorrect range in test cycle. Fix it and adjust test output accordingly.
