msm: usb_bam: make usb_bam_sps_type.usb_props a local variable

usb_bam_sps_type.usb_props is used only inside usb_bam_init().
Since this function is called several times usb_props values get
overriden each time. Making usb_props a local variable will prevent
potential bugs in the future in case usb_props is referenced elsewhere.
