firmware: tegra: bpmp: Return directly after a failed kzalloc() in get_filename()
[ Upstream commit 1315848f1f8a0100cb6f8a7187bc320c5d98947f ]
The kfree() function was called in one case by
the get_filename() function during error handling
even if the passed variable contained a null pointer.
This issue was detected by using the Coccinelle software.
Thus return directly after a call of the function “kzalloc” failed
at the beginning.
