char: hpet: add checks after calling ioremap
[ Upstream commit b11701c933112d49b808dee01cb7ff854ba6a77a ]
The function hpet_resources() calls ioremap() two times, but in both
cases it does not check if ioremap() returned a null pointer. Fix this
by adding null pointer checks and returning an appropriate error.
