NFC: NCI: Fix max length of General Bytes in ATR_RES
The maximum size of ATR_REQ and ATR_RES is 64 bytes.
The maximum number of General Bytes is calculated by
the maximum number of data bytes in the ATR_REQ/ATR_RES,
substracted by the number of mandatory data bytes.
ATR_REQ: 16 mandatory data bytes, giving a maximum of
48 General Bytes.
ATR_RES: 17 mandatory data bytes, giving a maximum of
47 General Bytes.
Regression introduced in commit a99903ec.
