[PATCH] mmc: core: style fixes in mmc.c

[Bhimeswararao Matsa]

Fix a couple of style issues reported by checkpatch.pl:

- Replace `#ifdef CONFIG_MMC_TRACE` with `if (IS_ENABLED(CONFIG_MMC_TRACE))`
  to follow the preferred kernel style for config-dependent branches.
- Drop explicit zero initialization of a static variable.

No functional change intended.
