[PATCH -next] crypto: chtls - remove set but not used variable 'csk'

[YueHaibing]

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

drivers/crypto/chelsio/chtls/chtls_cm.c: In function 'chtls_disconnect':
drivers/crypto/chelsio/chtls/chtls_cm.c:408:21: warning:
 variable 'csk' set but not used [-Wunused-but-set-variable]
 
drivers/crypto/chelsio/chtls/chtls_cm.c: In function 'chtls_recv_sock':
drivers/crypto/chelsio/chtls/chtls_cm.c:1016:23: warning:
 variable 'tcph' set but not used [-Wunused-but-set-variable]
 
'csk' and 'tcph' are never used since introduce
in commit cc35c88ae4db ("crypto : chtls - CPL handler definition")
