usb_bam: Acquire usb_bam_lock spinlock before lpm handshake spinlock

Currently driver is acquiring lpm handshake spinlock first before taking
usb_bam_lock spinlock in consumer request callback provided to IPA driver.
But releasing in reverse order. This could cause deadlock in corner case,
where as part of connect, notify_usb_connected() will be called with
usb_bam_lock acquired. If consumer request resource called from IPA driver,
first it takes lpm handshake spinlock and waits for other spinlock.
Hence fix the issue by acquiring usb_bam_lock first before taking lpm
handshake spinlock in consumer request resource callback provided to IPA
driver.
