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.

Not sure if 'alloc_size' can overflow in real life application, but using
the correct type looks harmless.
Should it be a real fix, either:
Fixes: 8cce437fbb5c ("s390/kdump: Fix elfcorehdr size calculation")
or
Fixes: 60a0c68df263 ("[S390] kdump backend code")
