LU-10391 lnet: remove 'accept' variable.

LU-10391 lnet: remove 'accept' variable.

lnet/acceptor.c has two variables, "accept" and "accept_type",
which have identical content and purpose.
Remove "accept" and just use "accept_type".

As the module parameter "accept" will now represent the value stored
in the variable "accept_type", we need to use module_param_named() to
allow the module parameter to have a different name to the kernel
variable.
