cxgb4: fix sleep in atomic when flashing PHY firmware
Before writing new PHY firmware to on-chip memory, driver queries
firmware for current running PHY firmware version, which can result
in sleep waiting for reply. So, move spinlock closer to the actual
on-chip memory write operation, instead of taking it at the callers.
