Subject: [PATCH 3/3] NFC: fdp: remove set but not used variable 'client'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/nfc/fdp/i2c.c: In function ‘fdp_nci_i2c_irq_thread_fn’:
drivers/nfc/fdp/i2c.c:205:21: warning: variable ‘client’ set but
not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
