Andy Shevchenko 76c67eb7e9 lib/vsprintf: Check pointer before dereferencing in time_and_date() ...

[ Upstream commit 372a12bd5d ]

The pointer may be invalid when gets to the printf(). In particular
the time_and_date() dereferencing it in some cases without checking.

Move the check from rtc_str() to time_and_date() to cover all cases.

Fixes: 7daac5b2fd ("lib/vsprintf: Print time64_t in human readable format")
