efi_loader: avoid out of bound access in efi_get_variable()
In efi_get_variable() a string is longer than the allocated space which results in overwriting the linked list of malloc(). The prefixes used for variables are 41 characters long, e.g. efi_67029eb5-0af2-f6b1-da53-fcb566dd1ce6_ Change PREFIX_LEN to 41.
