[PATCH] partitions/efi.c: replace useless kzalloc's by kmalloc's

[PATCH] partitions/efi.c: replace useless kzalloc's by kmalloc's

[Philippe De Muyter]

In alloc_read_gpt_entries and alloc_read_gpt_header, the kzalloc'ated
zones are either totally overwritten by the following read_lba call,
or freed.  As kmalloc is cheaper than kzalloc, use kmalloc.
