Subject: NFC: st-nci: Fix incorrect spi buffer size
From: Christophe Ricard <christophe.ricard@gmail.com>
commit a1269dd116319335db6d73013a31c038486c813e upstream.
When sending data over SPI, the maximum expected length is the maximum
nci packet payload + data header size + the frame head room (1 for the
ndlc header) + the frame trail room (0).
