lib/vsprintf.c: fix handling of %zd when using ssize_t
Documentation/printk-formats.txt says to use %zd for a ssize_t argument and some drivers do. Unfortunately this prints a positive number for negative values eg: tpm_tis 70030000.tpm_tis: tpm_transmit: tpm_send: error 4294967234 Add a case to va_args a ssize_t type if the interpretation should be signed. Tested on PPC32.
