NFC: st-nci: i2c: Drop two useless checks in ACPI probe path 



When st_nci_i2c_acpi_request_resources() gets called we already
know that the entries in ->acpi_match_table have matched ACPI ID
of the device.
In addition I2C client pointer cannot be NULL in any case
(otherwise I2C core would not call ->probe() for the driver in
the first place).

Drop the two useless checks from the driver.
