[POWERPC] Fix VDSO gettimeofday() when called with NULL struct timeval
Consider the prototype for gettimeofday():
int gettimofday(struct timeval *tv, struct timezone *tz);
Although it is valid to call with /either/ tv or tz being NULL, and
the C version of sys_gettimeofday() supports this, the current version
of gettimeofday() in the VDSO will SEGV if called with a NULL tv.
This adds a check for tv being NULL so that it doesn't SEGV.
