x86/mcelog: Add compat_ioctl for 32-bit mcelog support
A 32-bit version of mcelog issuing ioctls on /dev/mcelog causes errors like the following: MCE_GET_RECORD_LEN: Inappropriate ioctl for device This is due to a missing compat_ioctl callback. Assign to it compat_ptr_ioctl() as a generic implementation of the .compat_ioctl file operation to ioctl functions that either ignore the argument or pass a pointer to a compatible data type.
