xtensa: userspace: remove saving HiFi registers for syscalls

Browse source 
This removes the call to _xtensa_hifi_save() to save the HiFi
registers during syscalls. During syscall, we are not doing
context switching, and technically it is still the same thread.
There is no need to save HiFi registers.
