Borys Popławski 5277e3d633 x86/sgx: Add overflow check in sgx_validate_offset_length() 
[ Upstream commit f0861f49bd946ff94fce4f82509c45e167f63690 ]

sgx_validate_offset_length() function verifies "offset" and "length"
arguments provided by userspace, but was missing an overflow check on
their addition. Add it.
