Subject: [PATCH v2] usb: musb: use the new %pa format specifier for dma_addr_t

This patch makes use of the new format specifier %pa that was introduced
by the following commit.

7d7992108d02aa92ad4c77e5d9ce14088c942e75
("lib/vsprintf.c: add %pa format specifier for phys_addr_t types")

The addition of urb->transfer_dma and urb->actual_length is also done a
few lines below. I have moved this code up and pass the variable buf to
dev_dbg.

v2: Remove 0x from string as it will print as 0x0x
This applies on top of commit 43d5ad743c6f
("usb: musb: host: fix build warning")
I also added braces to the else statement for consistency.
(Didn't want to send a separate patch for that)
