[PATCH] Openvswitch: datapath.c: Fixed coding style warnings.

[Janusz Wolak]

Removed: block comments trailing without separate line,
missing blanks after decarations, comparasion to NULL, assignment in if
condition, not necessary spaces after a casts, multiple assignments, line
over 80 characters, alignment not matched to open parenthesis, kmalloc with
multiplying instead kmalloc_array.
