serial: clear serial info struct before calling ioctl()

Browse Source 
We need the kernel driver to give a proper value for the 'closing_wait'
variable, but don't assume it will.

This should solve the following kind of issues reported by valgrind:

==8985== Conditional jump or move depends on uninitialised value(s)
==8985==    at 0x4409A6: mm_serial_port_close (mm-serial-port.c:932)
==8985==    by 0x41A420: disable_all_done (mm-generic-cdma.c:753)
==8985==    by 0x4125A4: mm_manager_shutdown (mm-manager.c:1130)
==8985==    by 0x40DE35: main (main.c:203)
