[PATCH v2] staging: nvec: Remove unused NVEC_PHD macro

[Mohammed Guermoud <mohammed.guermoud@gmail.com>]

The NVEC_PHD macro is a debugging helper that is only enabled when
NVEC_PS2_DEBUG is defined. As this flag is never defined in the kernel,
the macro and all of its call sites are dead code.

As suggested by Greg Kroah-Hartman, removing the code is the cleanest
solution. This also fixes a build error discovered by the kernel test
robot after the v1 patch modified the macro's body.
