NFC: st21nfcb: Retry i2c_master_send if it returns a negative value

[ Upstream commit d4a41d10b2cb5890aeda6b2912973b2a754b05b1 ]

i2c_master_send may return many negative values different than
-EREMOTEIO.
In case an i2c transaction is NACK'ed, on raspberry pi B+
kernel 3.18, -EIO is generated instead.
