Building the SGX code with W=1 generates below warning:

  arch/x86/kernel/cpu/sgx/main.c:741: warning: Function parameter or struct member 'low' not described in 'sgx_calc_section_metric'
  arch/x86/kernel/cpu/sgx/main.c:741: warning: Function parameter or struct member 'high' not described in 'sgx_calc_section_metric'
  ...

The function sgx_calc_section_metric() is a simple helper which is only
used in sgx/main.c.  There's no need to use k-doc style comment for it.

Downgrade to normal comment to silence this warning.

x86/sgx: Fix a W=1 build warning in function comment

Building the SGX code with W=1 generates below warning:

  arch/x86/kernel/cpu/sgx/main.c:741: warning: Function parameter or
  struct member 'low' not described in 'sgx_calc_section_metric'
  arch/x86/kernel/cpu/sgx/main.c:741: warning: Function parameter or
  struct member 'high' not described in 'sgx_calc_section_metric'
  ...

The function sgx_calc_section_metric() is a simple helper which is only
used in sgx/main.c.  There's no need to use kernel-doc style comment for
it.

Downgrade to a normal comment.
