[neard][PATCH v2 54/73] unit: fix memory leaks in test-ndef-parse

[Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>]

[-- Attachment #1: Type: text/plain, Size: 3930 bytes --]

test-ndef-parse.c was not freeing fully the ndef records it got.
Replace the open-coded freeing with usage of near_ndef_records_free() to
solve libasan errors like:

    Direct leak of 8 byte(s) in 1 object(s) allocated from:
        #0 0x7f678a64b518 in calloc (/usr/lib/x86_64-linux-gnu/libasan.so.5+0xe9518)
        #1 0x557597045e89 in parse_sp_payload src/ndef.c:1468
        #2 0x557597045e89 in near_ndef_parse_msg src/ndef.c:2921

and valgring errors like:

    2 bytes in 1 blocks are definitely lost in loss record 2 of 52
