bug#35062: [PATCH v3 1/3] Remove redundant comparison

[Konstantin Kharlamov]

* src/xterm.c (x_set_frame_alpha): due to preceding checks it is bound
to be 0 ≤ alpha ≤ 1. (Bug#35062)
---
v3: mention functions changed in commit messages, mention the bug
number, and don't mention that it fixes a warning since intention  of
changes is clear either way.
