[PATCH] staging: sm750fb: Remove redundant NULL and zero assignments in probe

[Temitope obabi <obabitemitope765@gmail.com>]

The sm750_dev structure is allocated with devm_kzalloc() just above,
so its memory is already zeroed. Remove the explicit NULL assignments
to fbinfo[0] and fbinfo[1] and the zero assignment to mtrr.vram, which
only set fields that are already zero.

Note: Greg replied to my earlier sm750fb patch that keeping the
explicit zero assignments is good because it is clear what is
happening. In that patch the allocation was in a different function.
Here the assignments are in lynxfb_pci_probe(), just after the
devm_kzalloc() call and its NULL check, so I think removing them may
still be useful.
