alpha-ecoff: check archive element size

Browse Source 
If we run out of file before decompression finishes, the archive is
broken.  Don't allow the buffer to be returned with uninitialised data.

	* coff-alpha.c (alpha_ecoff_get_elt_at_filepos): Return an
	error if the full element size can't be decompressed.
