You're right, fixes tag is not necessary.
I made this change because I'm including the header to set_memory.c, and
IMHO it is better to make sure when possible that we get compilation errors
than linker errors, if for some reason kernel did not have SGX support.
It's also incoherent that KVM specific functions are compilation flagged but
sgx_set_attribute() is not.
