Subject: serial: sunhv: Free memory when remove() is called
X-Git-Tag: v4.10-rc1~149^2~12

serial: sunhv: Free memory when remove() is called

In each call to hv_remove(), con_read_page and con_write_page is not
getting freed and lead to memory leakage. Fix this by freeing both
pointers in hv_remove().
