[PATCH v4 3/3] Documentation: deprecated.rst: kmalloc-family: mark argument as optional

[Manuel Ebner <manuelebner@mailbox.org>]

put the optional argument (gfp) in square brackets
add default value = GFP_KERNEL

eg. ptr = kmalloc_obj(*ptr, gfp);
 -> ptr = kmalloc_obj(*ptr [, gfp] );

+The argument gfp is optional, the default value is GFP_KERNEL.
 If `ptr->flex_member` is annotated with __counted_by(), the allocation
 will automatically fail if `count` is larger than the maximum
 representable value that can be stored in the counter member associated
