[PATCH BlueZ] attrib: Fix interactive gatttool Segfault

From: Sathish N <redacted>

passing the special character single quote

$gatttool -I
[   ][                 ][LE]> '
Segmentation fault (core dumped)

Checking g_shell_parse_argv fail status(return FALSE on failure), works fine.

hope the fix to the previous "git am" error is solved
