[PATCH -next] x86/sgx: Make symbol 'sgx_vepc_vm_ops' static

[Wei Yongjun]

The sparse tool complains as follows:

arch/x86/kernel/cpu/sgx/virt.c:95:35: warning:
 symbol 'sgx_vepc_vm_ops' was not declared. Should it be static?

This symbol is not used outside of virt.c, so this
commit marks it static.

For the future:

Avoid having "This patch" or "This commit" in the commit message. It is
tautologically useless.

Also, do

$ git grep 'This patch' Documentation/process

for more details.

Thx.

The only reason I cannot ack this is that instead telling what the
commit does, the long description asks should this be done or not.
