[PATCH net v1] dim: initialize all struct fields

[Jesse Brandeburg <jesse.brandeburg@intel.com>]

The W=2 build pointed out that the code wasn't initializing all the
variables in the dim_cq_moder declarations with the struct initializers.
The net change here is zero since these structs were already static
const globals and were initialized with zeros by the compiler, but
removing compiler warnings has value in and of itself.

lib/dim/net_dim.c: At top level:
lib/dim/net_dim.c:54:9: warning: missing initializer for field ‘comps’ of ‘const struct dim_cq_moder’ [-Wmissing-field-initializers]
   54 |         NET_DIM_RX_EQE_PROFILES,
      |         ^~~~~~~~~~~~~~~~~~~~~~~
In file included from lib/dim/net_dim.c:6:
./include/linux/dim.h:45:13: note: ‘comps’ declared here
   45 |         u16 comps;
      |             ^~~~~

and repeats for the tx struct, and once you fix the comps entry then
the cq_period_mode field needs the same treatment.

Add the necessary initializers so that the fields in the struct all have
explicit values.

While here and fixing these lines, clean up the code slightly with
a conversion to explicit field initializers from anonymous ones, and fix
the super long lines by removing the word "_MODERATION" from a couple
defines only used in this file.
anon to explicit conversion example similar to used in this patch:
- struct foo foo_struct = { a, b}
+ struct foo foo_struct = { .foo_a = a, .foo_b = b)
