cxgb4/ch_ipsec: Replace the module name to ch_ipsec from chcr

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.
