[PATCH v3 23/46] net: Simplify parse_args()

[Simon Glass]

This function repeats the same code in a few places, namely setting
net_boot_file_name_explicit and copying of the filename to
net_boot_file_name

Move these two operations to the caller, with just the filename (or
NULL) returned by parse_args()

This makes things a little easier to follow.
