CVE-2026-45896

mtd: intel-dg: Fix accessing regions before setting nregions

In the Linux kernel, the following vulnerability has been resolved:

mtd: intel-dg: Fix accessing regions before setting nregions

The regions array is counted by nregions, but it's set only after
accessing it:

[] UBSAN: array-index-out-of-bounds in drivers/mtd/devices/mtd_intel_dg.c:750:15
[] index 0 is out of range for type '<unknown> [*]'

Fix it by also fixing an undesired behavior: the loop silently ignores
ENOMEM and continues setting the other entries.
