mtd: spinand: fix NULL pointer dereference in spinand_support_vendor_ops()
The spinand_support_vendor_ops() helper unconditionally dereferences
info->vendor_ops. For chips that do not define vendor_ops, this pointer
is NULL, leading to a kernel panic during probe:
Unable to handle kernel NULL pointer dereference at virtual address
0000000000000008
Add a guard to return early when vendor_ops is NULL. This prevents the
crash and allows SPI NAND devices without vendor-specific operations to
be probed correctly.
