[PATCH 1/4] EDAC: Fix calculation of returned address and next offset in edac_align_ptr()

[Eliav Farber <farbere@amazon.com>]

Do alignment logic properly and use 'ptr' for calculating the remainder
of the alignment.

This became an issue because 'struct edac_mc_layer' has a size that is
not zero modulo eight, and the next offset that was prepared for the
private-data was unaligned, causing an alignment exception.
