Subject: crypto: chelsio - remove set but not used variable 'kctx_len'
Patch-mainline: v5.0-rc1
Git-commit: 3cc04c160208ec55940db652343d236515d88af5
References: bsc#1136353 jsc#SLE-4688

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

drivers/crypto/chelsio/chcr_ipsec.c: In function 'chcr_ipsec_xmit':
drivers/crypto/chelsio/chcr_ipsec.c:674:33: warning:
 variable 'kctx_len' set but not used [-Wunused-but-set-variable]
  unsigned int flits = 0, ndesc, kctx_len;

It not used since commit 8362ea16f69f ("crypto: chcr - ESN for Inline IPSec Tx")
