MFC: r237101

Fix a braino in r236469 (MFC'ed to stable/9 in r236468); the number of
DMA tags required for handling MAXPHYS should be based on PAGE_SIZE rather
than SYM_CONF_DMA_BOUNDARY.
While at it, reuse the SYM_CONF_MAX_SG macro for specifying the maximum
number of DMA tags so sym(4) itself doesn't size memory beyond what's
required for handling MAXPHYS.
