wimax/i2400m: use -EL3RST to indicate device reset instead of -ERESTARTSYS
When the i2400m device resets, the driver code will force some
functions to return a -ERESTARTSYS error code, which can is used by
the caller to determine which recovery actions to take.
However, in certain situations the only thing that can be done is to
bubble up said error code to user space, for handling.
However, -ERESTARSYS was a poor choice, as it is supposed to be used
by the kernel only.
As such, replace -ERESTARTSYS with -EL3RST; as well, in
i2400m_msg_to_dev(), when the device is in boot mode (following a
recent reset), return -EL3RST instead of -ENODEV (meaning the device
is in bootrom mode after a reset, not that the device was
disconnected, and thus, normal commands cannot be executed).
