Fixes regression in 8faece5f

When using the ecryptfs_xattr_metadata mount option, eCryptfs stores the
metadata (normally stored at the front of the file) in the user.ecryptfs
xattr.  This causes ecryptfs_crypt_stat.num_header_bytes_at_front to be
0, since there is no header data at the front of the file.  This results
in too much memory being requested and ENOMEM being returned from
ecryptfs_write_metadata().

This patch fixes the problem by using the num_header_bytes_at_front
variable for specifying the max size of the metadata, despite whether it
is stored in the header or xattr.

USB 3 and Wireless USB specify a logarithmic encoding of the endpoint
interval that matches the USB 2 specification.  usb_fill_int_urb() didn't
know that and was filling in the interval as if it was USB 1.1.  Fix
usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case
alone, because David Vrabel wants to keep the old encoding.

Update the struct urb kernel doc to note that SuperSpeed URBs must have
urb->interval specified in microframes.

Add a missing break statement in the usb_submit_urb() interrupt URB
checking, since wireless USB and SuperSpeed USB encode urb->interval
differently.  This allows xHCI roothubs to actually register with khubd.

Contrary to the comment in fsg_add, fsg_bind calls fsg_unbind on errors,

The recent commit (0e530b45) that moved usb_ep_autoconfig from the
__devinit section to the __init section missed the mass storage device.
Its fsg_bind() function uses the usb_ep_autoconfig() function from non
__init context leading to:
WARNING: drivers/usb/gadget/g_mass_storage.o(.text): Section mismatch in
	reference from the function _fsg_bind()
	            to the function .init.text:_usb_ep_autoconfig()

The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY.
However, it has no ULPI support - so there are no registers at all.
That means accesses to ULPI_BUSCONTROL have to be abstracted away
like other MUSB registers.

This fixes building for Blackfin parts again.
