[linux-nfc] [neard][PATCH 15/16] nfctype5: fix returning uninitialized stack value in t5_tag_is_ti_pro()

The return value was not initialized so if tag was not matching, random
stack value (usually true) was returned instead of false.

This fixes clang warning:

    plugins/nfctype5.c:257:6: error: variable 'ret' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
            if ((uid[5] == 0xc4) || (uid[5] == 0xc5))
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    plugins/nfctype5.c:261:9: note: uninitialized use occurs here
            return ret;
                   ^~~
    plugins/nfctype5.c:257:2: note: remove the 'if' if its condition is always true
            if ((uid[5] == 0xc4) || (uid[5] == 0xc5))
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    plugins/nfctype5.c:248:10: note: initialize the variable 'ret' to silence this warning
            bool ret;
                    ^
                     = false
