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

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.
