[PATCH v2 2/2] NFC: nxp-nci: don't print header length mismatch on i2c error

[Michael Walle <michael@walle.cc>]

Don't print a misleading header length mismatch error if the i2c call
returns an error. Instead just return the error code without any error
message.

changes since v1:
 - reworded commit message
 - removed fixes tag
 - removed nfc_err() call, as it is done elsewhere in this driver
 - nxp_nci_i2c_fw_read() has the same issue. also handle it there
