Fix build errors when TLS=m, TLS_TOE=y, and CRYPTO_DEV_CHELSIO_TLS=y.
Having (tristate) CRYPTO_DEV_CHELSIO_TLS depend on (bool) TLS_TOE
is not strong enough to prevent the bad combination of TLS=m and
CRYPTO_DEV_CHELSIO_TLS=y, so add a dependency on TLS to prevent the
problematic kconfig combination.
Fixes these build errors:

When chtls_sock *csk is freed, same memory can be allocated
to different csk in chtls_sock_create().
csk->cdev = NULL; statement might ends up modifying wrong
csk, eventually causing kernel panic.
removing (csk->cdev = NULL) statement as it is not required.

This patch changes the module name to "ch_ipsec" and prepends
"ch_ipsec" string instead of "chcr" in all debug messages and
function names.
V1->V2:
-Removed inline keyword from functions.
-Removed CH_IPSEC prefix from pr_debug.
-Used proper indentation for the continuation line of the function
arguments.
V2->V3:
Fix the checkpatch.pl warnings.

As CHELSIO_INLINE_CRYPTO is bool, and CHELSIO_T4 is tristate, the
dependency of CHELSIO_INLINE_CRYPTO on CHELSIO_T4 is not sufficient to
protect CRYPTO_DEV_CHELSIO_TLS and CHELSIO_IPSEC_INLINE. The latter two
are also tristate, hence if CHELSIO_T4=n, they cannot be builtin, as
that would lead to link failures like:
drivers/net/ethernet/chelsio/inline_crypto/chtls/chtls_main.c:259: undefined reference to `cxgb4_port_viid'
and
drivers/net/ethernet/chelsio/inline_crypto/ch_ipsec/chcr_ipsec.c:752: undefined reference to `cxgb4_reclaim_completed_tx'
Fix this by re-adding dependencies on CHELSIO_T4 to tristate symbols.
The dependency of CHELSIO_INLINE_CRYPTO on CHELSIO_T4 is kept to avoid
asking the user.

As ch_ipsec was removed without clearing xfrmdev_ops and netdev

triggered by changing tls feature(tls-hw-tx-offload) from user

While CHELSIO_INLINE_CRYPTO is a guard symbol, and just enabling it does
not cause any additional code to be compiled in, all configuration
options protected by it depend on CONFIG_CHELSIO_T4. Hence it doesn't
make much sense to bother the user with the guard symbol question when
CONFIG_CHELSIO_T4 is disabled.
Fix this by moving the dependency from the individual config options to
the guard symbol.
