LU-6210 lnet: Change positional struct initializers to C99

LU-6210 lnet: Change positional struct initializers to C99

This patch makes no functional changes.  Struct initializers in the
lnet directory that use C89 or GCC-only syntax are updated to C99
syntax.  Whitespace is corrected to match coding style guidelines.

C89 positional initializers require values to be placed in the
correct order. This will cause errors if the fields of the struct
definition are reordered or fields are added or removed. C99 named
initializers avoid this problem, and also automatically clear any
values that are not explicitly set.

The following struct initializers have been updated:

lnet/include/lnet/lib-lnet.h:
	struct libcfs_ioctl_handler ident
	struct kvec diov (2 occurrences)
	struct kvec siov (2 occurrences)

	static struct rcadata rd[RCA_EVENTS]
