usb: gadget: udc: Remove useless variable assignment in xudc_read_fifo()

Browse Source 
This patch removes the unused variables assignment warning.
Value assigned to variable bufferspace is overwritten, before
it can be used. This makes such variable assignment useless.

Reported Coverity warning: UNUSED_VALUE
