Subject: [PATCH AUTOSEL 6.4 09/16] s390/crash: use the correct type for memory allocation

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit f471c6585c7f2f168b8eb2d19e2d6e5f22a6645f ]

get_elfcorehdr_size() returns a size_t, so there is no real point to
store it in a u32.

Turn 'alloc_size' into a size_t.
