Avoid calculating array size twice in kexec_purgatory_setup_sechdrs().
Once using array_size(), and once open-coded.
Flagged by Coccinelle:
.../kexec_file.c:881:8-25: WARNING: array_size is already used (line 877) to
compute the same size
No functional change intended.
Compile tested only.

A kexec kernel bootup hang is observed on Intel Atom cpu due to unmapped
EFI config table.
Currently EFI system table is identity-mapped for the kexec kernel, but EFI
config table is not mapped explicitly:
