arm: tegra: comms: Fix race condition in probe function.
XMM modem baseband character driver, which is used to download
modem software, had race condition. If USB host stack has
not enumerated XMM modem boot rom yet, then driver aborts module
load.
With this change, I/O (such as downloading modem software) will
be delayed until USB host stack has enumerated modem boot rom.
