module: merge repetitive strings in module_sig_check()
[ Upstream commit 705e9195187d85249fbb0eaa844b1604a98fbc9a ]
The 'reason' variable in module_sig_check() points to 3 strings across
the *switch* statement, all needlessly starting with the same text.
Let's put the starting text into the pr_notice() call -- it saves 21
bytes of the object code (x86 gcc 10.2.1).
