lib/vsprintf: refactor duplicate code to special_hex_number()
special_hex_number() is a helper to print a fixed size type in a hex
format with '0x' prefix, zero padding, and small letters. In the module
we have already several copies of such code. Consolidate them under
special_hex_number() helper.
There are couple of differences though.
It seems nobody cared about the output in case of CONFIG_KALLSYMS=n,
when printing symbol address, because the asked field width is not
enough to care last 2 characters in the string represantation of the
pointer. Fixed here.
The %pNF specifier used to be allowed with a specific field width,
though there is neither any user of it nor mention the possibility in
the documentation.
