[PATCH 4/5] efi_loader: Clean up usage of structure jmp_buf_data

[Heinrich Schuchardt]

From: Yao Zi <ziyao at disroot.org>

Structure jmp_buf_data provides the underlying format of jmp_buf, which
we actually don't care about. Clean up existing code to use the standard
jmp_buf type. This introduces no functional change.
