Commit 5c4e8d3781bc ("usb: host: xhci-tegra: Add support for XUSB
context save/restore") is using the IPFS 'num_offsets' value when
allocating memory for FPCI context instead of the FPCI 'num_offsets'.
We have not observed any specific issues because of this, but could
cause too much memory or too little memory to be allocated. Fix this
by using the FPCI 'num_offsets' for allocating the FPCI memory for
storing the FPCI state.
