[XFS] Map EFSCORRUPTED to an actual error code, not just a made up one 


(990).	Turns out some ye-olde unices used EUCLEAN as
Filesystem-needs-cleaning, so now we use that too.

 * XXX EFSCORRUPTED needs a real value in errno.h. asm-i386/errno.h won't

 *     return codes out of its known range in errno.

 * XXX Also note: needs to be < 1000 and fairly unique on Linux (mustn't

 *     conflict with any code we use already or any code a driver may use)

 * XXX Some options (currently we do #2):

 *	1/ New error code ["Filesystem is corrupted", _after_ glibc updated]

 *	2/ 990 ["Unknown error 990"]

 *	3/ EUCLEAN ["Structure needs cleaning"]

 *	4/ Convert EFSCORRUPTED to EIO [just prior to return into userspace]
