LU-6210 obd: Change positional struct initializers to C99

LU-6210 obd: Change positional struct initializers to C99

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

The C99 syntax prevents incorrect initialization if values are
accidently placed in the wrong position, allows changes in the struct
definition, and clears any members that are not given an explicit
value.

The following struct initializers have been updated:

lustre/obdclass/lprocfs_jobstats.c:
	static const struct seq_operations lprocfs_jobstats_seq_sops
lustre/obdclass/obd_config.c:
	struct llog_process_cat_data
lustre/obdclass/obd_mount.c:
	struct lustre_mount_data2 lmd2 (2 occurrences)
