Fix timeouts in sys_pselect7
Since we (Analog Devices) updated our Blackfin kernel to 2.6.28, we've seen occasional 5-second hangs from telnet. telnetd calls select with a NULL timeout, but with the new kernel, the system call occasionally returns 0, which causes telnet to call sleep (5). This did not happen with earlier kernels. The code in sys_pselect7 looks a bit strange, in particular the variable "to" is initialized to NULL, then changed if a non-null timeout was passed in, but not used further. It needs to be passed to core_sys_select instead of &end_time. This bug was introduced by 8ff3e8e85fa6c312051134b3953e397feb639f51 ("select: switch select() and poll() over to hrtimers").
